Electric-field-assisted magnetization switching in FePd/Pb(Mg 1/3Nb2/3)O3-PbTiO3 heterostructure at room temperature

Abstract

We demonstrate an electric-field-assisted magnetization switching in FePd/PMN-PT heterostructure at room temperature. Not only the remanent magnetization but also the coercivity exhibits an obvious response with the electric field. Without the aid of magnetic bias field, the remanent magnetization of the FePd film shows an analogous on-off behavior with the electric field switching on and off alternatively. The magnetization switching can be electrically controlled in this heterostructure due to the variation of coercivity caused by electric field. © 2013 AIP Publishing LLC.
