It has been shown that the transition temperature of superconducting lanthanum is lowered when a given fraction of lanthanum is replaced by another rare earth, a quantity dependent on the spin of the dissolved atom (Matthias et al. Phys. Rev. Letters 1, 449(1958)). This effect can be explained if the exchange interaction between the conduction electrons and the 4f electrons is considered. The equation for the transition temperature is derived on this basis. (J.S.R.)
