Extractions: Superconductivity and its applications About superconductors About superconductors Superconductivity was first observed in 1911 by the Dutch physicist Heike Kamerlingh Onnes ( Nobel laureate 1913 ). When he cooled a mercury sample to the temperature of liquid helium (4.2 K), its resistance suddenly disappeared. This means that the material is able to conduct currents without any energy losses - a remarkable feature. He also discovered that this dissipation-free state of matter, named superconductivity, was destroyed by high currents and external magnetic fields. The next milestone in understanding superconductivity occurred in 1933, when Walter Meissner and Robert Ochsenfeld discovered that a superconductor will repel an external magnetic field. The currents induced in in a surface layer of a superconductor by a magnet placed close to it exactly mirror the field that otherwise would have penetrated the superconducting material, creating a zero field inside the material. This means that a superconductor can be considered as a perfect diamagnet. The effect is ususally referred to as the "Meissner effect" - an effect that is so strong that a magnet can be levitated above the surface of a superconductor. The Meissner effect is more fundamental for a superconductor than the zero resistance. Since the discovery of superconductivity, scientists have tried to find new materials with even higher transition temperature
Extractions: VOL. 23, NO. 9 NOVEMBER 14, 1997 B Y B OB N ELSON team of researchers from Columbia's Lamont-Doherty Earth Observatory and IBM have developed a technology that can find tiny quantities of superconducting materials in a soup of other products. By using a combination of high-technology methods, which they call "scanning SQUID petrology," the scientists were able to detect superconducting or magnetic materials at concentrations of less than 1 part per million in samples weighing a fraction of a microgram, or millionth of a gram. They were also able to show that a widely-used method of synthesizing superconductors is likely to be contaminated by chlorine, which had been thought to be inert in this reaction. The new technology will help researchers more readily identify and extract superconductors, extremely efficient electrical conductors that are expected to have wide application in transportation, energy and science once they are perfected. "Scanning SQUID petrology can be applied to other materials science problems to identify superconducting compounds at low concentrations in complex mixtures," said Bruce Scott, manager for chemistry and materials science at IBM, adjunct senior research scientist at Lamont and a member of the research team.
