Abstract
Considerable effort1 has been directed toward obtaining an understanding of the observed variation of the superconducting transition temperature of a metal on the addition of impurities in terms of the details of their magnetic character. Technetium would appear to be an interesting and experimentally convenient superconducting transition metal solvent for comparison with theory. It has both a high transition temperature (7.8°K), thus making unnecessary the very low-temperature techniques needed to study such solvents as ruthenium and iridium, and an apparently high mutual solubility with the “magnetic” 3d elements.2 The 3d elements are not expected to possess well-defined local moments in solution in technetium due to technetium’s position in group VII of the periodic table,3,4 but we are unable to anticipate how closely they will approach the nonmagnetic limit.
Research sponsored jointly by the United Kingdom Atomic Energy Authority and the U.S. Atomic Energy Commission under contract with the Union Carbide Corporation.
