- 論文の詳細を見る
The superconducting transition temperature, T_c, the magnetic susceptibility and lattice constants were measured. T_c strongly depends upon the density of states at the Fermi surface estimated from the magnetic susceptibility. The electron interaction parameter of the Bardeen-Cooper-Schrieffer theory of superconductivity was found to be approximately 0.09 eV/atom for all the compounds investigated. The dependence of the volume of unit cell upon electron concentration is similar to that of T_c and the density of states over the concentration range investigated. These results are consistent with a two-band model of superconductivity in transition metals, proposed by J. Kondo.
