Abstract

Measurements of the depressions of the superconducting transition temperature Tc with Sm impurity concentration and the specific heat jump at Tc as a function of Tc, and the temperature dependences of the normal state specific heat and magnetic susceptibility are reported for the matrix impurity system (LaSm)Sn3. The results constitute the first definitive evidence of a Kondo effect for a dilute alloy containing Sm impurities.
