摘要

Electric-field-modulated magnetic properties are investigated on FeSi films with a (0 1 1) preferred orientation on (0 1 1) 0.7[Pb(Mg1/3Nb2/3)O-3]-0.3[PbTi0.3O3] (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 degrees magnetic easy axis direction transition of the FeSi film, we also achieve electric-fieldmediated giant 180 degrees magnetization switching with the assistance of the magnetic field pulse.
