Adventures in characterising magnetic high entropy oxide thin films

La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 is a high entropy perovskite oxide which has attracted interest due to the ability to switch between antiferromagnetic and ferromagnetic ground states by varying its Mn concentration.

We have grown thin films of this material, and using X-ray, electron, and neutron diffraction, examined how it changes under different epitaxial strain conditions

About the presenter

Kayla Lord is a PhD student at the University of New South Wales, working with CI Nagy Valanoor. She is currently researching the magnetic properties of high entropy perovskites, and past research has focused on resistive switching and resonant tunnelling in ferroelectric thin films. This work fits in FLEET’s research theme 1, Topological materials.
