ABSTRACT
This paper theoretically analyzes the Andreev reflection in normal-conductor/multi-band super-conductor junctions. We applied Bogoliubov-de Gennes equations to the case of superconductors with extended s-waves and calculated the respective point-contact Andreev reflection (PCAR) spectra. Our results showed that the PCAR measurement with high-Tc superconductivity can be used as a tool for measuring the spin-polarization of ferromagnetic materials.
