Spin injection dependent metamagnetic transition

TL;DR

This paper introduces a mechanism where spin injection from a ferromagnetic to a metamagnetic metal induces a non-equilibrium chemical potential shift, effectively controlling a metamagnetic phase transition.

Contribution

It proposes a new way to control metamagnetic transitions using spin injection, linking spin transport to phase change in magnetic materials.

Findings

Spin injection can induce a metamagnetic transition.

Chemical potential shifts act as an effective magnetic field.

Control of magnetic phase transitions via spin currents.

Abstract

We define the metamagnetic phase transition of itinerant electrons controlled by the spin injection mechanism. The current flow between a ferromagnetic metal and a metamagnetic metal produces the non-equilibrium shift of chemical potential for spin up and spin down electrons that acts as an effective magnetic field driving the metamagnetic transition.
