Abstract: The electric field manipulation of magnetic properties is currently of great interest for the opportunities provided in low-energy-consuming spintronics devices. Here, the effect of electric field on magnetic and crystalline structure of the ferromagnetic LSMO thin film which is epitaxially grown on PMN-PT ferroelectric substrate is investigated. With the application of electric field on the sample, the crystalline structure, polarization, magnetization and Curie temperature are effectively modified. The mechanism of the electric field manipulation of these properties is ascribed to the strain mediation and charge mediation caused by the polarization. Based on 109。and 71。ferroelastic domain switching of the substrate, non-volatile magnetism can be achieved, which is closely related to the relative proportion of in-plane polarization vectors and induced distinct in-plane strain states after domain switching.
