Proximity effects near the interface between d-wave superconductors and ferro/antiferromagnets

Abstract

We study the proximity effects near the interface between a d-wave superconductor (S) and a ferromagnet (F) or an antiferromagnet (AF). The S-side (F and AF-side) is described by the attractive (repulsive) Hubbard model, and the Bogoliubov de Gennes equation derived within the Hartree-Fock approximation is solved numerically. The superconducting order parameter and the magnetization (m) can coexist near the interface, and the spatial variation of m induces the spin-triplet p-wave component in both F and AF cases. The local density of states is also calculated and discussed.
