Abstract

We report results of Mössbauer and X-ray diffraction measurements on powdered samples of (Zn, Cd) x Fe1.7−x Co0.9Ti0.4O4 spinel oxides (where x=0 to 1.0) obtained at about 300 K. The spectra for both Zn- and Cd-substituted spinel oxides transform with increase in x from ordered magnetic state to disordered spin-state. Lattice parameters, density and porosity of the samples are also reported. Analysis of Mössbauer spectra shows that Zn and Cd ions occupy both tetrahedral and octahedral sites.
