Investigations on electrical and magnetic properties of multiferroic [(1-x)Pb(Fe0.5Nb0.5)O3xNi0.65Zn0.35Fe2O4] composites

Here, we report the magnetic, ferroelectric, dielectric properties, and Raman spectroscopic studies of multiferroic [(1-x)Pb(Fe0.5Nb0.5)O-3-xNi(0.65)Zn(0.35)Fe(2)O(4)] composites at room temperature. The phase formation of composites was confirmed independently from the X-ray diffraction and Raman studies. The room temperature magnetic studies reveal ferromagnetic like behavior of these composites in contrast to the paramagnetic nature of Pb(Fe0.5Nb0.5)O-3. Furthermore, with increasing x, the saturation magnetization, remnant magnetization, and coercive fields are found to increase. The electrical characterizations of these composites reveal a decrease in remnant polarization and dielectric constant with increasing x. More importantly, the x=0.2 composite is found to be a very good multiferroic material at room temperature among the composites and could be a potential candidate for future potential applications.
