Electric field-induced tuning of magnetism in PbFe_(0.5)Nb_(0.5)O_3 at room temperature

摘要

We study the influence of electrical poling, carried out at room temperature, on the structure and magnetism of Pb(Fe_(0.5)Nb_(0.5))O_3 by analyzing the differences observed in structural and magnetic properties before and after the electrical poling. The changes observed in magnetization of Pb(Fe_(0.5)Nb_(0.5))O_3 before and after electrical poling exhibit considerably strong converse magnetoelectric effect at room temperature. In addition, the strengthening of Fe/Nb-O bond due to electrical poling is discussed on the basis of Raman spectral studies and analysis of neutron diffraction patterns. The potential tunability of magnetization with electrical poling can be an ideal tool for realization of application potential of this multiferroic material.
