Abstract

Proximity effects near the interface between d-wave superconductors (S) and ferromagnets (F) or antiferromagnets (AF) are studied. The S (F and AF) side is described by the attractive (repulsive) Hubbard model, and the Bogoliubov de Gennes (BdG) equation is derived within a Hartree–Fock approximation. By solving the BdG equation numerically we find that the spin-triplet p-wave component Δ p appears both in F and AF cases. The Δ p is induced by the coupling to the spatial variation of m so that it shows the oscillatory behavior in the AF case.
