Abstract
Mössbauer, X-ray diffraction, dc magnetization and ac susceptibility measurements have been carried out in the spinel ferrite GaxFe1−xNiCrO4 (0≤x≤1) in different temperature ranges between 1.4 and 700 K. These measurements show A site occupation of Fe3+ ions and a coexistence of ferrimagnetic and frustrated (entropic) spins in this system for all x. The frustration in this system arises due to the random distribution of Fe3+ and diamagnetic Ga3+ ions on the A sites, and those of Ni2+ and Cr3+ ions on B sites.
