Abstract

The impact of cation composition on the magnetic properties in the InFeMO₄ mixed spinel system (M=Mg,Co,Ni) has been studied by means of AC/DC magnetization and ⁵⁷Fe Mössbauer spectroscopy measurements. Existence of a glassy state was confirmed for InFeCoO₄ by AC magnetization measurement, whereas the shape of the hysteresis loop in M - H measurement suggests the presence of strong interactions between the magnetic clusters. Soft magnet-type behaviour was observed for InFeNiO₄ with the value of saturation magnetization suggesting the presence of canted spin structure as a consequence of the presence of nonmagnetic indium. In the case of InFeMgO₄ the further magnetic dilution due to nonmagnetic magnesium was observed to lead to clear decay in long-range magnetic order, although the presence of short-range magnetic order was confirmed by M - H and ⁵⁷Fe Mössbauer measurements.
