Abstract
By taking into account of the Kondo effect, the spatial variation of the order parameter in superconductors containing a single magnetic impurity is discussed. We use the method of the double-time Green function used by Zuckermann, and Takano and Matayoshi, and follow the methods of Zittartz, Müller-Hartmann and Kondo to solve the equation for the t-matrix. The spatial variation of the order parameter is obtained by a method similar to that of Heinrichs. Only the case, in which the temperature is very close to Tc and |ln TK/T| = |τ| (TK: Kondo temperature) is very large, is considered. The spatial variation of the order parameter is considered up to the terms of the order of (1/τ)3. The main effect is to replace γ2 by 1/τ2 is expression of the spatial variation of the order parameter and of the transition point. The term 1/τ3 yields the asymmetry for τ> 0 and τ≪ 0, i.e. T ≪TK and T ≫TK.
