This paper reports a voltage-controlled nonvolatile 90° magnetization rotation and voltage-assisted 180° magnetization reversal in a spin-valve multiferroic heterostructure. By using the strain-mediated magnetoelectric coupling effect, the magnetic moment of the free layer can be manipulated by an electric field. The critical magnetic field required for complete 180° magnetization reversal can be tremendously reduced. Accordingly, a large and nonvolatile magnetoresistance modulation was achieved.
