Andreev reflection measurements of spin polarization
We discuss aspects of Andreev reflection AR measurements in normal metal-superconductor N-S and ferromagnet-superconductor F-S devices. We describe the analytical model used to quantify spin polarization from the conductance measurements and discuss the validity of this simple model using parabolic bands as simple surrogates for real band structures. We present AR measurements of spin polarizat...
متن کاملProbing spin polarization with Andreev reflection: A theoretical basis
Andreev reflection at the interface between a ferromagnet and a superconductor has become a foundation of a versatile technique of measuring the spin polarization of magnetic materials. In this article we will briefly outline a general theory of Andreev reflection for spin-polarized systems and arbitrary Fermi surface in two limiting cases of ballistic and diffusive transport. © 2001 American I...
متن کاملSpin accumulation and Andreev reflection in a mesoscopic ferromagnetic wire
The electron transport though ferromagnetic-metal–superconducting hybrid devices is considered in the nonequilibrium Green’s function formalism in the quasiclassical approximation. Attention is focused on the limit in which the exchange splitting in the ferromagnet is much larger than the superconducting energy gap. Transport properties are then governed by an interplay between spin accumulatio...
متن کاملAndreev reflection resonant tunneling through a precessing spin
We investigate Andreev reflection (AR) resonant tunneling through a precessing spin which is coupled to a normal metallic lead and a superconducting lead. The formula of the AR conductance at zero temperature is obtained as a function of chemical potential and azimuthal angle of the spin precessing by using the nonequilibrium Green function method. It is found that as the local spin precesses i...
