Abstract

The ferrite of composition Cu0.5Fe2.5O4, prepared using a conventional solid-state processing route, was soaked at different temperatures between 1200°C and 1350°C, for an hour, in air. The samples were rapidly quenched into oil. Mössbauer, resistivity and x-ray lattice parameter data were obtained for the quenched phase. The maximum saturation magnetization value, obtained at 10K, was close to 5.0μB. The characterization of the sample showed Cu+1 to be partially disordered across both A and B sites of the spinel structure, with an excess occupancy of the A-site showing that under the proper conditions the ordered high 4πMs Cu+1 phase will be stable.
