# Strain and thickness effects on magnetocrystalline anisotropy of CoFe(011) films

## TL;DR

This study examines how strain and thickness influence the magnetocrystalline anisotropy of CoFe(011) thin films, revealing that strain modifies the easy axis and MCA energy through electronic structure changes.

## Contribution

It provides new insights into the strain-dependent behavior of MCA in CoFe(011) films, linking electronic structure features to magnetic anisotropy variations.

## Key findings

- Perpendicular MCA energy increases with compressive strain.
- In-plane MCA becomes an easy axis under tensile strain.
- Electronic structure explains MCA behavior changes.

## Abstract

We investigate MCA of CoFe(011) thin films as a function of strength of strain and film thickness has been studied. It is elucidated that perpendicular magnetocystalline anisotropy (MCA) energy (EMCA) is getting stronger with compressed xy-plane lattice constant while in-plane MCA is become an easy-axis by tensile strain on xy-plane. The reason of the EMCA behaviors can be explained by features of electronic structures.
