| Description |
Magnetoelectric (ME) composites xNiFe(2)O(4)-(1-x)Na0.5Bi0.5TiO3 (x = 0.10,0.30,0.50) were synthesized by conventional solid state reaction method. Crystal structure and microstructural characteristics of these composites were investigated by XRD and SEM respectively. Rietveld analysis of XRD pattern confirms the coexistence of cubic (Fd3m) and rhombohedral (R3c) symmetry simultaneously in these composites. The microstructural evaluation discloses the effect of constituent phases on the average grain size of a composite. The dielectric constant (epsilon') and dielectric loss (tan delta) were examined as a function of frequency within range (100 Hz to 7 MHz) and at different temperatures. The magnetic behavior of composites was determined by MH hysteresis loop which reveals their soft magnetic behavior. ME voltage coefficient was determined to study the coupling between ferrite and ferroelectric phases. The maximum value of ME coefficient alpha approximate to 223 mu V/cmOe was observed for 0.10NFO-0.90NBT sample.
