Effect of allied and alien ions on the EPR spectrum of Mn4+-containing lithium-manganese spinel oxides

Electron paramagnetic resonance spectroscopy was used for studying the effect of allied and alien ions on the EPR spectrum of Mn4+-containing lithium-manganese spinel oxides. Manganese spinel oxides with paramagnetic Mn4+ and diamagnetic substituents in the 16d spinel sites were studied: Li[Mg0.5Mn1.5]O4, Li[Mg0.5−xCo2xMn1.5−x]O4, 0
