摘　　要：Multiferroic materials, which have coexisting magnetism and ferroelectricity, are of great technological and fundamental importance. Researchers from the Key Laboratory of Materials Physics, Institute of Solid State Physics, Chinese Academy of Sciences, Hefei, ChinaMultiferroic materials, which have coexisting magnetism and ferroelectricity, are of great technological and fundamental importance. Researchers from the Key Laboratory of Materials Physics, Institute of Solid State Physics, Chinese Academy of Sciences, Hefei, China have sought the origin of the giant tetragonal ferroelectric distortion and the nature of the pressure-induced spin-state transition in the potentially multiferroic material BiCo03. The present study, in strong contrast to some recent works, provides an insight into this potentially multiferroic material.
