Abstract
The effect of Anderson impurities on proximity effect tunneling into two-band metals such as palladium is studied. The Yamada-Yosida approach is used to treat the Anderson impurities in the two-band metal. In the Kondo region, it is shown that the pair-breaking parameter for the d band mimics the pair-breaking parameter in the Müller-Hartmann and Zittartz theory for low-Kondo-temperature alloys (Tc≫TK) but deviates from it for high-TK alloys. The change in the transition temperature of the proximity effect sandwich due to the presence of Anderson impurities in the two bands of the normal side appears to be similar to that obtained by Kaiser except for the presence of the new pair-breaking parameter. © 1983 Plenum Publishing Corporation.
