Andreev conductance of a ferromagnet-superconductor point contact

Abstract

Based on the boundary conditions derived for quasiclassical Green's functions, a theory of Andreev reflection in ferromagnet-superconductor point contacts is constructed. From a comparison with experimental data, the polarization of the conduction band was estimated for a number of ferromagnetic materials used in experiments on Andreev spectroscopy. © 2003 MAIK "Nauka/Interperiodica"
