Title: The electric field manipulation of magnetization in La{sub 1−x}Sr{sub x}CoO{sub 3}/Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}-PbTiO{sub 3} heterostructures

Abstract

La{sub 1−x}Sr{sub x}CoO{sub 3} (x = 0.18, 0.33, and 0.5) films were grown epitaxially on piezoelectric Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}-PbTiO{sub 3} substrates by pulsed laser deposition. The magnetization of these films varies with the external electric field, showing the magnetoelectric effect. With different doping content of Sr{sup 2+} ions, the change of magnetization for these films show different behaviors with increasing temperature, which can be attributed to the competition between electric-field-induced changes of spin state and double exchange interaction. This work presents an alternative mechanism to investigate the electric field control of magnetism in magnetoelectric heterostructure by tuning the spin state.
