Abstract
The effect of sintering time variation on grain size, density, porosity, dc electrical resistivity, activation energy, drift mobility, dielectric constant, loss factor, maximum magnetic flux density and coercivity of Cu 0.6Zn 0.4Fe 2O 4 ferrites has been reported. Grain size, density and drift mobility increased with the increase in sintering time. Porosity, dc electrical resistivity and activation energy decreased with the increase in sintering time. Dielectric constant decreased by increasing frequency for all the samples and it follows the Maxwell–Wagner's interfacial polarization. Loss factor was also studied. It has a decreasing trend followed by resonance peak with the rise of frequency.
