MULTIFERROIC STRUCTURE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A multiferroic structure and a method for manufacturing the same are provided to omit a buffer layer by eliminating the shrinkage difference of a ferroelectric layer and a ferromagnetic layer. CONSTITUTION: A ferroelectric(2) is one or more selected from a group including K_1-xNa_xNbO_3 ceramics, K_1-xNa_xNbO_3 ceramics, Li_x(K_0.5Na_0.5)_1-xNb_1-ySb_yO_3, and Ag_x(K_0.5Na_0.5)_1-xNbO_3. A ferromagnetic(3) is one or more selected from a group including NiFe_2O_4 ferrite, Ni_1-xZn_xFe_2O_4 ferrite, Co_1-xZn_xFe_2O_4 ferrite, and CoFe_2O_4 ferrite. A ferroelectric layer and a ferromagnetic layer are alternately stacked to form a multiferroic structure(1).
