On the Newtonian origin of the spin motive force in ferromagnetic atomic wires

TL;DR

This paper demonstrates through numerical simulations that a spin-motive force arises in ferromagnetic atomic wires with precessing domain walls, explained by adiabatic dynamics applicable to both classical and quantum systems.

Contribution

It provides the first numerical evidence of the spin-motive force in one-dimensional ferromagnetic wires with dynamic internal fields, emphasizing its adiabatic origin.

Findings

Spin-motive force exists in 1D wires with precessing domain walls.

The effect is explained by adiabatic dynamics.

Applicable to both classical and quantum systems.

Abstract

We demonstrate numerically the existence of a spin-motive force acting on spin-carriers when moving in a time and space dependent internal field. This is the case of electrons in a one-dimensional wires with a precessing domain wall. The effect can be explained solely by considering adiabatic dynamics and it is shown to exist for both classical and quantum systems.
