Cation Distributions and Magnetic Properties of Ferrispinel MgFeMnO4

The research deals with spinel compounds MgFeMnO4, which is known as a cathode material of magnesium battery. It exhibits a cationic disordering in cubic spinel structure and ferrimagnetism at room-temperature. The experimental data is acquired using a combination of magnetization, Mössbauer spectroscopy measurements, powder diffractions and muon spin rotation, relaxation and resonance (μ+SR) techniques.
