Abstract X-ray, magnetization, susceptibility and Mössbauer spectroscopic measurements have been performed on the Co-Ca ferrite system, Ca x Co1−x Fe2O4. The measurements show that a solid solution is possible only for x〈0.2. Thereafter the system shows a mixture of two phases. The variations in lattice constant and Néel temperature are explained on the basis of calcium substitution. The decrease in magnetization in the mixed phases is due to an increase of paramagnetic phase and decrease of ferrimagnetic phase with concentration. The Mössbauer spectra at 300 and 77 K support the concept of mixed phases.
