Over the last few years, the X-ray magnetic circular dichroism (XMCD) technique has evolved into an important magnetometry tool. This paper is an overview of the principles and unique strengths of the technique. Aspects covered include the quantitative determination of element-specific spin and orbital magnetic moments and their anisotropies through sumrule analyses of experimental spectra. A discussion is presented on how the spin and orbital magnetic moments in transition-metal thin films and sandwiches are modified relative to the bulk. We show that a thin film of a nonmagnetic metal such as Cu may become magnetically active when adjacent to a magnetic layer, and a thin film of a

B uilding on our ability to manipulate the magnetic properties of atoms in two-dimensions , we have turned our synthesis efforts to address an important problem in condensed matter physics - the unusual physics that result from the placement of spins on a low dimensional magnetically frustrated lattice. A kagomé lattice, which is composed of vertex sharing triangles, presents an ideal construct for studying this problem in magnetism. We are exploring jarosite compounds of the formula AM O(OH) (SO (A = monovalent ion, M = magnetic trivalent ion), which have been long recognized as ideal model kagomé lattices. M (OH) triangles (panel (a)) are linked at their corners to form the triangular kagomé lattice in a 2-dimensional hexagonal network (panel (b)). The sulfate capping groups alternately point up and down about the hexagonal network. The kagomé layers are separated by A ions (panel (c)). P rior to our work, jarosite-type materials had escaped precise magnetic characterization over the past three decades because they are notoriously difficult to prepare in pure and crystalline forms. These hurdles have been overcome with our development of new redox-based hydrothermal methods . Armed with pure and crystalline materials, several perplexing issues surrounding the magnetic properties of the jarosites have been resolved

HOME SITE HELP ABOUT SEARCH ... EDUCATIONAL English Swedish October 7, 2003 The quantum physics that controls the micro-world has a wide range of spectacular effects that do not normally occur in our ordinary macro-world. There are, however, certain situations in which quantum phenomena are visible. This year's Nobel Prize in Physics is awarded for work concerning two of these situations: superconductivity and superfluidity. Alexei Abrikosov and Vitaly Ginzburg have developed theories for superconductivity and Anthony Leggett has explained one type of superfluidity. Both superconductivity and superfluidity occur at very low temperatures. Flow without resistance An unexpected cold effect When investigations were first carried out into the nature of electricity in the 19th century, it was evident that metals and certain alloys conduct electricity by allowing electrons to move between the atoms. But the disorganised way in which the electrons move causes the atoms to vibrate, so heat is generated. If the current is too strong, the heat can be so great that the conductor melts. In addition it was found that an electric current through a conductor creates a magnetic field, which in turn generates current in the opposite direction. Electricity and magnetism interact and can thus counteract each other. In 1911 the Dutch physicist Heike Kamerlingh Onnes made a remarkable discovery. He was particularly interested in the properties of substances at low temperatures and had succeeded in producing liquid helium, which has an extremely low temperature. When Onnes investigated the electric conductivity of mercury, he found that when the metal was cooled by means of liquid helium to a few degrees above absolute zero, its electric resistance vanished. He named this phenomenon

Kim and Y-C Chung Affilation: Hanyang University, KR Pages: Keywords: ab initio, DMS, energetic stability, magnetic moment Abstract: Some diluted magnetic semiconductors (DMS), in which magnetic elements are substituted for a small fraction (~5%) of host elements in a semiconductor lattice, show ferromagnetism, and thus possess potential applicability in spintronics. To obtain quantum-mechanical understanding of electronic and spin structure, we have performed ab initio total energy calculations on IV:TM (IV=SiC, Si, Ge, TM=V, Cr, Mn, Fe, Co, Ni). We used the generalized gradient approximation (GGA) to describe the exchange-correlation interaction between the electrons, and incorporated the projector augmented wave (PAW) potential to simulate the electron-ion interaction. The stability of the ferromagnetic phase in SiC-, Si-, and Ge-based DMS is investigated comprehensively. From the energetics, we found that IV:TM reveals ferromagnetism for the case of V, Cr, Mn, and Fe. The origin of the magnetism will be discussed in terms of the density of states and the wave function characters around the Fermi level.

The History of Magnets Figure 1: Location of Magnets in a Typical Modern Car What is magnetism, anyway? Magnetism is the response of materials towards an applied magnetic field. Fundamentally, the magnetic properties of matter are the result of microscopic atomic currents which produce magnetic moments in matter. The origin of this atomic current is the orbital and spin motion of electrons around the nucleus.... a permanent source of current. Free atoms of some elements may have zero magnetic moment because the various orbital and spin components completely cancel each other. However, the magnetic properties of any material in bulk depend not only on the magnetic moment of the free atoms or molecules, but also on temperature and on the complicated inter-atomic forces in condensed matter. Apart from the electronic magnetic moment, the protons and neutrons (or nucleons) of atoms have also magnetic moments associated with them, but these are small compared with those of electronic origin. Magnetism is generally classified into three different categories: ferromagnetism (highly positive response) paramagnetism (very small positive response) diamagnetism (small negative response) We can exploit any type of magnetism if we know how. For example, the paramagnetism of water in our body is exploited for imaging as a diagnostic medical tool using the nuclear magnetic resonance property of the proton in water molecule, known as the MRI technique (see Figure 2).

Abstract In this paper we describe a method for growing high-purity single-grain R-Mg-Cd quasicrystals. For Rare Earth (R) elements Dy, Tb, and Gd, we report dc magnetization data taken from single quasicrystals. These quasicrystals demonstrate a temperature dependence that obeys the Curie-Weiss law at elevated temperatures, T > 50 K, and a freezing behavior similar to canonical spin-glasses at low temperatures. In particular, the quasicrystal Gd-Mg-Cd displays an unusual correlation between its freezing temperature and the strength of magnetic interactions in comparison to Tb and Dy quasicrystals. Introduction The arrangement of atoms in a conventional crystal is both ordered and periodic. In other words, all the atomic positions within a crystal can be described by an integer set of translation of a unit cell. Symmetry and the requirement that all of space be tiled limits the number of allowed crystal lattices.

77. Magnetic And Transport Properties Of High-Tc Superconductors We have studied the effects of doping on a set of magnetic properties, namely,spin excitations, susceptibility, and staggered magnetization, within the tJ http://cftc.cii.fc.ul.pt/RESEARCH/IP/HTSC.htm

Magnetism of High Temperature Superconductors The discovery of superconductivity in the doped copper oxides has stimulated the study of the magnetism in these materials, both because of its intrinsic interest and its connection to high temperature superconductivity. The undoped parent compounds are antiferromagnetic (AF) insulators. The long-range AF order is rapidly destroyed with doping, and upon further doping the system becomes superconducting, while short-range AF correlations still persist. The copper oxide materials are strongly anisotropic, both with respect to their transport and magnetic properties. It is widely believed that the CuO planes are responsible for the properties of those materials. Doping introduces holes which are the charge carriers in the AF square lattice of the CuO planes. The simplest model that seems to contain the physics of the CuO planes is the t-J model, which describes holes moving in a Heisenberg spin system. In this system the holes are strongly coupled to the spin array, the motion of holes generating spin fluctuations. A striking feature of the copper oxides is the strong sensitivity of their magnetic properties to hole concentration. Our work has been concerned with the understanding of this aspect. We have studied the effects of doping on a set of magnetic properties, namely, spin excitations, susceptibility, and staggered magnetization, within the t-J model. Quantum many-particle techniques were used to calculate the renormalization of the magnetic properties induced by the hole-magnon interaction. We found that those properties strongly depend on doping due to the hole-magnon interaction generated by hole motion, our results showing good agreement with experimental data on the copper oxide high temperature superconductors.

CRYSTAL-LATTICE DISORDER EFFECTS IN ELECTRONIC, MAGNETIC, AND SUPERCONDUCTING PROPERTIS OF METALS AND COMPOUNDS Group members: Prof. Boris I. Belevtsev (Head of the Group) Dr. Nina V. Dalakova Dr. Yevgeniy Yu. Belyaev Mr. Igor I. Logvinov Subjects of scientific researches: In general: influence of crystal-lattice disorder on transport, superconducting and magnetic properties of solids. Specifically: - weak and strong electron localization in solids, - metal-insulator transitions, - influence of radiation damage on superconducting and magnetic properties, - interplay of superconductivity and magnetism. Objects of studies: metals, semimetals, mixed-valence perovskite manganites and cobaltites, high- T c superconductors, rare earth nickel borocarbides, granular superconducting and magnetic metals and compounds. Main results: The study of anisotropy of kinetic and magnetic properties of La Ca MnO The pronounced anisotropy of electron transport and magnetic anisotropy in La Ca MnO films has been found. In particular, magnetoresistance (MR) depends non-monotonically on magnetic field H for both H perpendicular and parallel to the film plane. At low enough temperature, a positive MR was found in the field perpendicular to the film plane. The results obtained were considered taking into account two main sources of MR anisotropy: (1) the existence of preferential directions of magnetization (due to strains stemming from the lattice film-substrate mismatch or other reasons); (2) dependence of resistance on the angle between current and the magnetization, which is inherent in ferromagnets (so called anisotropic magnetoresitance (AMR)). It is found that manifestation of the latter effect (in particular, its temperature dependence) is quite different from that in
