Magnetoelectric (ME) effects for lanthanum modified BiFeO 3 ?PbTiO 3 (BE? x PT) solid solutions have been investigated. The value of magnetoelectric polarization coefficient, up is 10 times greater than that of Cr 2 O 3 . The results also show that up is due to a linear coupling between polarization and magnetization, and that up is independent of do magnetic bias and ac magnetic field. The ME effect is believed to be significantly enhanced due to breaking of the cycloidal spin state of a long-period spiral spin structure, via randomly distributed charged imperfections.
