Pair Correlations in a Clean Magnetic Josephson Junction

ORAL

Abstract

We study pair correlations in superconducting-magnetic proximity systems made of inhomogeneous nanoscale magnetic films sandwiched between two superconductors. In the ballistic regime, we solve the Bogoliubov-de Gennes equations for a tight binding Hamiltonian and calculate the Gor'kov functions of the system. The goal is to determine how different parameters of the model affect the generation and relative weight of all four pair correlation symmetry states (singlet, triplets). We also compare the generation of correlations in the clean and the diffusive regimes. Different magnetic configurations are considered to this effect.
