We investigate the exchange bias effect in a Mn50.12Ni39.31Sn10.57/0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) laminate. 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. (C) 2014 Elsevier B.V. All rights reserved.
