Abstract

MgFe2O4 was synthesized by using sol-gel auto-combustion technique and coupled with BaTiO3 using the conventional solid state reaction method with different weight fraction of x = 0.00, 0.02, 0.04, 0.06 and 0.08 to form (1-x)BaTiO3 - xMgFe2O4 composite. The structure, magnetic properties and complex impedance analysis of the composite samples were studied using X-ray diffraction technique (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM) and High-frequency response analyzer (HFRA) respectively. XRD patterns showed a single phase tetragonal BaTiO3 for each composition due to the very small amount of MgFe2O4. The hysteresis loop confirmed that the composite has soft magnetic properties by addition of MgFe2O4. Small coercive field, HC has been recorded and it decreased with the increasing of MgFe2O4 weight fraction. However, magnetization increased when the amount of MgFe2O4 is increased. Impedance analysis conducted in range of 0.1 Hz to 10 MHz showed two depressed semicircle arcs for samples with MgFe2O4 due to the resistive and capacitive behavior of the bulk and grain boundaries of the samples.
