Kondo impurities in strong coupling superconductors
Journal Article
·
· J. Low Temp. Phys.; (United States)
Generalized Eliashberg equations including the effects of Kondo impurities in strong coupling superconductors are given. The Kondo effect is treated using the Matsuura, Ichinose, Nagaoka (MIN) theory. The transition temperature T/sub c/ is calculated from the general equations by using the ''square well'' model for the electron-phonon interaction. Deviations of the present results from those of MIN are significant. In general, the depression of T/sub c/ by the impurities is softened.
