Hot isostatic pressing of wires made of magnesium diboride, or MgB2, significantly increased the amount of electrical current the wires can carry without electrical resistance. Wires made from MgB2 would reduce the costs of such products as MRIs and electrical generators, say the researchers: Adriana Serquis, Leonardo Civale, Xiaozhou Liao, J. Yates Coulter, Duncan Hammon, Yuntian Zhu, Dean Peterson and Fred Mueller from Los Alamos' Superconductivity Technology Center; and Vitali Nesterenko from the University of California, San Diego. They presented their findings on Dec. 3 at the Materials Research Society meeting in Boston.

High Temperature Superconductors Our department has an experimental research effort in the area of low-temperature physics, with emphasis on the study of the transport and magnetic behaviors of the high temperature superconductors. The picture at the right [from A. Sleight, Science 1519 (1988)] shows the structure of a typical such material. The high temperature superconductors represent a new class of materials which bear extraordinary superconducting and magnetic properties and great potential for wide-ranging technological applications. The importance of understanding the transport and magnetic behaviors of these novel materials is two-fold. First, it could lead to a better understanding of the basic phenomena of superconductivity in these materials. Second, it could provide ways to improve the magnetic quality of the presently known materials by enhancing flux pinning in a controllable manner. A current-carrying type II superconductor in the mixed state When a current is applied to a type II superconductor (blue rectangular box) in the mixed state, the magnetic vortices (blue cylinders) feel a force (Lorentz force) that pushes the vortices at right angles to the current flow. This movement dissipates energy and produces resistance [from D. J. Bishop et al., Scientific American, 48 (Feb. 1993)]. When a type II superconductor is placed in a magnetic field H < H < H , where H and H are the lower and upper critical fields, respectively, the magnetic vortices that penetrate the material should form a uniform triangular lattice (Abrikosov vortex lattice) with a lattice spacing determined by the strength of H. If H is increased, the vortices become more closely spaced and their cores start to overlap. At H

ALL TOP 20 Today, more than 140,000 wireless base stations are deployed across the U.S. Collectively, they provide service to more than 147 million people. As carriers have built out their footprints, wireless users have continued to gobble up capacity. Roughly half of the U.S. population now subscribes to mobile services. Intense competition and huge bundles encourage users to make more and more use of their wireless devices. As a result, minutes of use (MOUs) have skyrocketed. FIG. 1 Now, customers expect and even demand that their mobile phones have performance that is on par with landline devices. This attitude was enough to give carriers heartburn. Then, the carriers realized that greater wireless traffic has led to an associated rise in radio-frequency (RF) interference. RF interference directly contributes to a greater percentage of dropped calls, blocked calls, and origination failures. All of these outcomes negatively affect customer satisfaction. In the past, wireless carriers would address these network strains by building base stations and bringing them online to expand their capacity. CAPEX budgets have been trimmed, however, and communities have pushed back on carriers. Site selection and approval is now more difficult and costly.

High-temperature superconductivity The discovery of cuprate superconductors which are superconducting up to 150K has been a landmark in modern condensed matter physics. It has opened up new avenues in technology, from power generation to the non-destructive testing of aircraft wheels. It also presents a serious challenge to our theoretical understanding of metals: its behaviour does not fit in with the "standard model" for metal, the Landau Fermi liquid theory, which has served us well for the last 50 years. Structure of YBa Cu O Courtesy of Frank Hewat, ILL These systems consist of strongly correlated electrons moving in CuO planes. At half-filling, there is exactly one electron per unit cell. There is strong Coulomb repulsion between the electrons. This leads to an electronic traffic jam the ground state is an insulator. Exchange effects mean that electrons on neighboring sites prefer to have antiparallel spins, and so this insulator is antiferromagnet. This is depicted on the diagram below on the left hand side. The traffic jam can be relieved by removing electrons from the CuO planes. This is done by chemical doping. We now have a metal that conducts electricity. The mobile carriers are the vacancies (holes) moving in an antiferromagnetic background. Further doping eventually destroys the antiferromagnetic order, and one finds a range of doping where the system is a superconductor below a transition temperature

News for August 2005 The ups and downs of doping 11 August 2005 Finding a theory that explains high-temperature superconductivity in cuprate materials is one of the outstanding challenges in condensed-matter physics. Now a team of physicists in the US and Japan has observed a new effect that could help in the search for such a theory. Cuprate materials are normally insulators but they become superconductors when dopant atoms are added. However, Seamus Davis of Cornell University and colleagues have found evidence which suggests that these dopant atoms can also lead to electronic disorder that damages the superconducting properties of the cuprates ( Science Doping generally involves adding impurities or charge carriers - which can be electrons or "holes" - to inert materials. The challenge is to produce the required electronic properties in the material with the dopant atoms, which are randomly distributed, without causing electronic disorder. Davis and colleagues at Cornell, the University of California at Berkeley, the AIST laboratory in Tsukuba and the University of Tokyo studied crystals of bismuth strontium calcium copper oxide (Bi

Text-Only Privacy Policy Site Map Pushing the boundaries of high-temperature superconductors Yimei Zhu (left) and Robert Klie Click here for a high resolution photograph. A collaboration led by scientists at BNL has revealed a new mechanism that explains why adding calcium to a high-temperature superconductor increases its current-carrying capacity. The findings refute the current explanation and open the door for similar additives with potentially better current-boosting abilities. The study, which was supported by the Office of Basic Energy Sciences within DOE’s Office of Science, is published in the May 26, 2005, edition of Nature. In theory, high-temperature superconductors conduct electricity with no resistance. But the most practical, inexpensive high-temperature superconducting materials — those suitable for applications such as electronic devices and power lines — are made of many tiny crystalline grains. The boundaries between grains act like barriers to electric charge carriers, impeding the flow of current. This is the case for the superconducting material in this study, known as YBCO for its constituent elements: yttrium, barium, copper, and oxygen.

Text-Only Privacy Policy Site Map Understanding the mysteries of high-temperature superconductors The electronic states in a high-temperature superconducting material are strongest along the diagonal momentum direction. (Image by Donghui Lu) Click here for a high resolution photograph. High-temperature superconductors (HTSCs) operate in mysterious ways, but scientists are starting to understand their peculiarities by using a state-of-the-art spectroscopy system at SSRL. One of the biggest mysteries is how a material that starts as an insulator—which does not conduct electricity—can become a high-temperature superconductor after being doped with electric carriers. Researchers Kyle Shen and Donghui Lu (both ESRD), working in Zhi-xun Shen’s group at SSRL and Stanford, looked at the evolution from insulator to superconductor by studying an HTSC material at different doping concentrations, including ones that are insulating. The team used angle-resolved photoemission spectroscopy (ARPES), a method of probing the electronic states in solids. Their results, published in Science magazine on February 11, contribute to creating a fundamental understanding of the perplexing physics of HTSCs.
