Abstract

Abstract: Electric-field-modulated magnetic properties are investigated on FeSi films with a (0 1 1) preferred orientation on (0 1 1) 0.7[Pb(Mg1/3 Nb2/3 )O3 ]–0.3[PbTi0.3 O3 ] (PMN–0.3PT) single crystal substrates. When saturated and reversed coercive electric fields are alternately applied to the Pt/PMN–0.3PT/FeSi/Ta heterostructures, a reversible and non-volatile magnetic transition between four-fold and two-fold anisotropy is demonstrated by means of the angular dependence of remanent magnetization measurements. Based on the electric field control of the 90° magnetic easy axis direction transition of the FeSi film, we also achieve electric-field-mediated giant 180° magnetization switching with the assistance of the magnetic field pulse.
