Theory of Spin Hall Magnetoresistance from a Microscopic Perspective
Theory of Spin Hall Magnetoresistance from a Microscopic Perspective
We present a theory of the spin Hall magnetoresistance of metals in contact with magnetic insulators. We express the spin mixing conductances, which govern the phenomenology of the effect, in terms of the microscopic parameters of the interface and the spin–spin correlation functions of the local moments on the surface …
