Influence on interfacial diffusive scatterings of the angle between the magnetizations of the two magnetic layers in a magnetic trilayer

Abstract To understand the influence of the relative angle between the magnetizations of the two magnetic layers in a magnetic trilayer on diffusive scatterings of a transport electron, we study an A–B–C magnetic trilayer by use of the effective mean-free-path model. Our theoretical results indicate that varying the relative angle can enhance or suppress an interfacial diffusive scattering on a transport spin-dependent electron if the thickness of the metallic layer is smaller than the spin relaxation length.
