Impedance spectroscopy study on Mn1+x Fe2−2x Ti x O4 (0⩽x⩽0.5) ferrites

Abstract

The complex impedance spectroscopy and surface morphology of Mn1+x Fe2−2x Ti x O4 (0⩽x⩽0.5) system, prepared using a conventional solid state reaction technique, were investigated. The impedance spectroscopy measurements were carried out at room temperature in the frequency range of 42–5 MHz. The electrical processes in the samples were modeled in the form of an equivalent circuit made up of a combination of two parallel RC circuits attributed to grain and grain boundaries. The DC conductivity obtained by extrapolation of AC data using impedance spectroscopy and four-probe method increases at 10% doping of Ti ions. The energy-dispersive X-ray (EDX) pattern confirmed the homogeneous mixing of the Mn, Fe, Ti and O atoms in pure and doped ferrite samples.
