Self-organization of eight structurally and magnetically non-equivalent positions of manganese ions Mn2+ in a unit cell of single-crystal lithium-gallium spinel Li0,5Ga2,5O4 is demonstrated. The ions are self-distributed over these positions and the minima of the crystal field potential. Self-distribution of manganese ions becomes apparent in the spectra of Electron Paramagnetic Resonance (EPR).
