“…The incorporation of Cr into Mg ferrites has no pronounced effect on the dielectric constant in high frequency, but it significantly decreases in the low frequency range. This is in agreement with earlier observations This is in agreement with earlier observations of some other workers on Cr substituted spinel ferrites (Kuthari et al 1990, Bhaskar et al 2004. The dielectric behaviour of ferrites may be explained on the basis of the mechanism of dielectric polarization process and is similar to that of the conduction process.…”

The spinel ferrites MgCr x Fe 2-x O 4 (0.0    1.0) were prepared through the solid state reaction using conventional ceramic method at 1300C in air. The homogeneous phase of the ferrite samples was observed from the X-ray diffraction study. Lattice parameter of the samples was found to decrease with increasing Cr concentration in the system obeying Vegard's law. The ac electrical resistivity, measured as a function of temperature, decreases with the increase of temperature indicating the semiconducting nature of all the samples. The activation energies were calculated and found to decrease with increasing Cr content. The lower activation energies are associated with higher electrical conductivity. With the increase of temperature, dielectric constant () and dielectric loss tangent are observed to be increased; while with the increase of frequency, dielectric constant () and dielectric loss tangent decrease for all the samples.

“…The addition of stoichiometrically a small amount of Co (0.03) to Ni ferrite controls superparamagnetic behavior and increases resonance frequency significantly [8,9]. Similarly, small amount of Mn has been added to Ni ferrite to enhance saturation magnetization and to control magnetostriction coefficient [10]. In order to improve the density of Ni ferrite, small amount of Cu was added to it.…”
