Contribution

It introduces a mechanism for generating charge currents from pure spin currents in inhomogeneous, spin-dependent rings, expanding spintronic control methods.

Findings

Pure spin current injection induces charge current in a ring.

Charge current magnitude depends on spin-dependent transport coefficients.

Abstract

We show that the injection of a pure spin current (not accompanied by charge current) into a ring can induce a circulating charge current in the ring, provided that transport coefficients of the ring are spin-dependent and inhomogeneous. As an example, we consider a hybrid ferromagnet(F)-normal metal(N) ring system and calculate the magnitude of the charge current induced by the pure spin current injection. This phenomenon may have relevance for spintronic applications.
