摘要：The electric field manipulation of magnetic properties is currently of great interest for the opportunities provided in low-energy-consuming spintronics devices. Here, we report the effect of electric field on magnetic and transport properties of the ferromagnetic SrRuO₃ film which is epitaxially grown on Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ ferroelectric substrate. With the application of electric field on the substrate, the magnetization, Curie temperature and resistivity of SrRuO₃ are effectively modified. The mechanism of the electric field manipulation of these properties is ascribed to the rotations of RuO₆ oxygen octahedra caused by the electric-field-induced strain, which changes the overlap and hybridization between the Ru 4 d orbitals and O 2 p orbitals, resulting in the modification of the magnetic and electronic properties.
