Abstract

We fabricated a magnetoelectric laminate structure consisting of a magnetostrictive Tb_0.3Dy_0.7Fe_1.92 (Terfenol-D) plate bonded to a La_0.7Ca_0.15Sr_0.15MnO ₃ (LCSMO)/0.67Pb(Mg_1/3Nb_2/3)O ₃-0.33PbTiO₃ (PMN-PT) structure where a LCSMO film was epitaxially grown on a PMN-PT single crystal substrate. When a dc magnetic field is applied perpendicular to the film plane, the magnetoresistance of the LCSMO film in the paramagnetic (ferromagnetic) state for the LCSMO/PMN-PT/Terfenol-D structure is larger (smaller) than that for the LCSMO/PMN-PT structure without Terfenol-D. These effects are caused by the magnetostriction-induced in-plane compressive strain in the Terfenol-D, which are transferred to the PMN-PT substrate, leading to a reduction in the in-plane tensile strain of the epitaxial LCSMO film and thereby modifying the magnetoresistance of the film.
