- Abstract
Composites with compositions x (Ni0.8Co0.1Cu0.1Fe2O4) + (1− x) PbZr0.2Ti0.8O3 ( x-mole fraction varies as 0.15, 0.25, 0.35 and 0.45) were prepared by standard ceramic method. The presence of constituent phases, namely ferrite and the ferroelectric were confirmed by X-ray diffraction. The structural analyses were carried out using the obtained powder pattern X-ray data. The porosity of the samples was calculated and the values obtained lie between 10% to 19%. To date, the variations in the magnetic properties with variation in ferrite phase in composites and thereby its influence on magnetoelectric effect is not yet reported. The saturation magnetization ( Ms) and magnetic moment (ηB) in Bohr magneton were calculated for all the composites. The static value of magnetoelectric voltage coefficient ( dE/ dH) was measured as a function of intensity of magnetic field. The maximum value of ME coefficient was observed for a composite with 35% ferrite + 65% ferroelectric phase.
