我们研究了 Mn50.12Ni39.31Sn10.57/0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 层压板中的交换偏向效应。这种铁磁形状记忆合金的交换偏置场随着电场的施加而显着减小，表现出有趣的磁电效应。利用这一特性，可以通过电场在该叠层中切换磁化符号，而无需偏置磁场的帮助。讨论了交换偏置效应电场控制的起源。
We investigate the exchange bias effect in a Mn50.12Ni39.31Sn10.57/0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3laminate. The exchange bias field of this ferromagnetic shape memory alloy decreases remarkably with the application of electric field, showing an interesting magnetoelectric effect. Using this property, the magnetization sign can be switched in this laminate by electric field without the aid of bias magnetic field. The origin of electric-field control of exchange bias effect is discussed.
