Transport characteristics of ferromagnetic metal - insulator - superconductor: determination of spin polarization of conduction electrons
Main Article Content
Abstract
New method for determination of the spin polarization of conducting electrons of a ferromagnetic metal using a tunnel junction with a thin superconducting counter-electrode is proposed. An effect of the symmetry of the superconducting order parameter on the contact resistance has been analyzed.
