摘要

How magnetoelectric coupling actually occurs on a microscopic level in multiferroic BiFeO_3 is not well known. By using high-resolution single crystal neutron diffraction techniques, we have determined the electric polarization of each individual element of BiFeO_3, and concluded that magnetostrictive coupling suppresses the electric polarization at the Fe site below T_N. This negative magnetoelectric coupling appears to outweigh the spin current contributions arising from the cycloid spin structure, which should produce positive magnetoelectric coupling. antiferromagnetics
