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.
