We study the interplay between magnetic correlations of two Kondo impurities and superconducting singlet pairing. Performing a Schrieffer-Wolff transformation in the zero-bandwidth limit of the twoimpurity Anderson model we obtain the Hamiltonian of two magnetic impurities and we add a superconducti
We discuss the effect of multichannel Kondo impurities on superconductivity. In the strong coupling regime such impurities are pairbreakers, in contrast to the ordinary Kondo effect. Measurements of To-suppression may help in identifying impurities displaying this more exotic exchange coupling to th
