| Abstract | ||||
| Samples with the chemical formula MnGaxFe2-xO4 (x = 0.0, 0.1, 0.3, 0.5 and 0.7) were prepared by the usual ceramic method. X-ray analysis revealed the presence of single spinel phase. The lattice parameters as well as the porosity were found to decrease while the density and grain size were increased with increasing Ga concentration (x). The magnetization, the initial permeability and Curie temperature are decreased with increasing x. On the other hand, the dc electrical resistivity is increased with increasing Ga concentration. The results are explained according to the assumed cation distribution. | ||||
