Abstract

When superconductivity with spin-singlet Cooper pairing occurs in the presence of inhomogeneous magnetism, spin-triplet Cooper pairing amplitude occurs in addition to spin-singlet pairing amplitude, even when only a spin-singlet pairing interaction and pair potential occur. Mixing of spin-singlet and spin-triplet Cooper pairing is shown explicitly in k-space and r-space pairing amplitudes and in the electron spin susceptibility. The mixed pairing is associated with one-electron spinors which vary strongly in space over dimensions small compared to the size of a Cooper pair.
