Title: Structure, magnetic and complex impedance analysis of (1-x)BaTiO{sub 3}- xMgFe{sub 2}O{sub 4} composite

Abstract

MgFe{sub 2}O{sub 4} was synthesized by using sol-gel auto-combustion technique and coupled with BaTiO{sub 3} 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)BaTiO{sub 3} - xMgFe{sub 2}O{sub 4} 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 BaTiO{sub 3} for each composition due to the very small amount of MgFe{sub 2}O{sub 4}. The hysteresis loop confirmed that the composite has soft magnetic properties by addition of MgFe{sub 2}O{sub 4}. Small coercive field, HC has been recorded and it decreased with the increasing of MgFe{sub 2}O{sub 4} weight fraction. However, magnetization increased when the amount of MgFe{sub 2}O{sub 4} is increased. Impedance analysis conducted in range of 0.1 Hz to 10 MHz showed two depressed semicircle arcs for samples with MgFe{sub 2}O{sub 4} due to the resistive and capacitive behavior of the bulk and grain boundaries of the samples.
