Electron-electron-interaction in compensated ultra high-field superconductors

Abstract

According to a suggestion of Jaccarino and Peter [1] magnetic impurities in superconductors may be so coupled among themselves and with an external magnetic field that the paramagnetic effect partially cancels the external field [2]. In this model the indirect exchange between Cooper pairs arises from the exchange of virtual magnons. We calculate the size of this repulsive interaction and find it to be smaller than is assumed in [1].
