Magnetoelectric effect in PbCoTiFe10O19 multiferroic ceramic

Magnetoelectric hexaferrites have attracted more and more attention recently owing to their high operation temperature and large magnetoelectric effect. In this paper, we report the multiferroicity and magnetoelectric coupling in an M-type hexaferrite, PbCoTiFe10O19. The electric polarization of thi...

Description
Summary:Magnetoelectric hexaferrites have attracted more and more attention recently owing to their high operation temperature and large magnetoelectric effect. In this paper, we report the multiferroicity and magnetoelectric coupling in an M-type hexaferrite, PbCoTiFe10O19. The electric polarization of this multiferroics decreases sharply around 240K, which is consistent with the onset temperature of conical spin structure, suggesting the intrinsic coupling between magnetic and electric orders. Moreover, cross-control of magnetism and ferroelectricity is simultaneously realized in this magnetoelectric hexaferrite. The origin of magnetoelectric effect in PbCoTiFe10O19 is discussed.
