The polycrystalline samples of MgCrxFe2-xO4 ferrites were prepared
by the conventional solid state ceramic sintering technique in air.
The x-ray diffraction patterns obtained showed sharp peaks
indicating the formation of single phase cubic spinel structure.
Magnetic measurements were performed in order to investigate
different magnetic properties of the samples. The Curie temperature
(Tc) for all the samples has been determined where the Hopkinson
type of effect at Tc has been observed with the manifestation of a
sharp fall in permeability. The electrical resistivity measurements
have been carried out as a function of temperature. The activation
energies were found to be decrease with increasing Cr content. The
lower activation energies are associated with higher electrical
conductivity. The AC resistivity and dielectric constant of the
samples are found to decrease with increasing frequency, exhibiting
normal ferromagnetic behavior. The observed variation of electrical
and dielectric properties of MgCrxFe2-xO4 ferrites are explained on
the basis of Fe2+/Fe3+ ionic concentration.
