Impact of electric poling on structure, magnetism and ferroelectricity of 0.7PbFe0.5Nb0.5O3-0.3BiFeO3 multiferroic

In this paper we have discussed the impact of electric poling on structure, magnetism and ferroelectricity of 0.7PbFe0.5Nb0.5O3 - 0.3BiFeO3 (PBFN) multiferroic. Magnetization data exhibit the presence of strong converse magneto electric coupling in a material. The temperature dependent Raman measurements demonstrate considerable changes in Raman scattering intensity and spectrum structure around TC, indicating a structural change around TC. The octahedral stretching vibration modes revealed a remarkable frequency shift below TN and the anomalies are owing to the coupling interaction between the spin-phonons. Changes in Raman modes and magnetization data support the hypothesis of converse magnetoelectric coupling. By poling, the improvement in ferroelectric domain ordering occurs and it was confirmed by P-E loops. We present the implications of our investigation on electric poling of PBFN multiferroic in the current interest of spintronics.
