Spin current induced by the sound wave

TL;DR

This paper investigates how sound waves in a magnetic field can generate spin currents through resonant transverse spin conductivity in conduction electrons.

Contribution

It introduces the concept that longitudinal sound waves induce transverse spin conductivity with a resonant behavior in electron systems.

Findings

Longitudinal sound waves produce transverse spin conductivity.

The spin conductivity exhibits a resonant character.

Sound waves can be used to manipulate spin currents.

Abstract

The kinetics of conduction electrons interacting with the field of sound waves in a constant magnetic field is studied. It is shown that the longitudinal sound wave propagation occurs transverse spin conductivity, which has a resonant character.
