Combined Spin Valve and Anisotropic Magnetoresistance in NiFe/Cu/NiFe Layered Thin Films

Abstract

We present a theoretical study of the combined effect of spin valve and anisotropic magnetoresistance in NiFe/Cu/NiFe layered thin films, using an extended form of the semiclassical Camley and Barnás model for electron transport. The anisotropic magnetoresistance is treated by introducing spin-dependent anisotropic mean free paths in the NiFe layers. From calculations of both magnetoresistance effects as a function of NiFe and Cu thickness, we discuss the validity of a description of the combined effect in terms of a simple summation of spin valve and anisotropic magnetoresistance.
