Multiple magnetoelectric coupling effect in BaTiO3/Sr2CoMoO6 heterostructures

Abstract Due to the demand of controlling magnetism by electric fields for future storage devices, materials with magnetoelectric coupling are of great interests. Based on first-principles calculations, we study the electronic and magnetic properties of a double perovskite Sr2CoMoO6 (SCMO) in a hybr...
