Description :
Abstract: Dielectric properties of Mn-Zn nanoferrites such as dielectric constant(Ɛ’),dielectric loss(Ɛ’’) tangent and conductivity has been investigated in the frequency range 100Hz to 10MHz the variation in the above parameters of dielectric properties with frequency and temperature is explained qualitatively. The dielectric constant Mn0.5Zn0.5Fe2O4 is found to be less than the bulk sample.the migration of Fe3+ ion from octahedral site to tetrahedral site decreases the dielectric constant with increase in Mn consentration.The charge libration of charge and electron hopping mechanism can be explained together for the conduction mechanism in present compound . The formation of spinel structure and grain size was confirmed using X-ray diffraction technique and transmission electron microscopy (TEM) which confirmed by scaning electron microscopy (SEM).
