Tunnel magnetoresistance of magnetic junctions with cubic symmetry of the layers

TL;DR

This paper investigates the tunnel magnetoresistance (TMR) behavior in magnetic junctions with cubic symmetry layers, revealing an additional TMR peak at lower magnetic fields due to magnetic switching phenomena.

Contribution

It introduces a model for TMR in cubic symmetry magnetic junctions and analyzes the magnetic switching effects under perpendicular magnetic fields.

Findings

An additional TMR peak appears at lower magnetic fields.

Magnetic switching occurs at fields below the anisotropy energy of the soft layer.

The study provides insights into TMR behavior in cubic symmetry magnetic junctions.

Abstract

A tunnel magnetic junction is considered with magnetic hard and magnetic soft layers of cubic symmetry. The magnetic switching is analyzed of the layers by a magnetic field perpendicular to the initial magnetizations. In such a situation, an additional peak of the TMR ratio appears at the magnetic field value lower substantially than the anisotropy energy of the soft layer.
