Abstract

We use the technique of electron spin resonance (ESR) to analyze the distribution of cations in Mn _3-xNi _xO ₄with x = 0-1. ESR data suggest that Ni ²⁺ ions prefer to occupy octahedral-sites (B-sites) at low doping and concurrently produce a Mn ⁴⁺ ion in B-site. As Ni ²⁺ ions reach a critical value of ₀.5, partial tetrahedral-sites are replaced by Mn ³⁺ ions and form inverse spinel. Continually adding the Ni content up to x ∼ 1 results into a full transformation of structure into inverse spinel, which is accompanied with a drop of ESR intensities.
