The enhanced magnetodielectric interaction of (1 − x)BaTiO3–xCoFe2O4 multiferroic composites

Abstract

Multiferroic composites containing barium titanate (BaTiO₃) and cobalt ferrite (CoFe₂O₄) were synthesized by a simplified one pot solid-state reaction process, in which all of the basic chemicals (BaCO₃, TiO₂, Fe₂O₃, CoO) were directly mixed together. Compared with the conventional two step solid-state reaction process, this simplified process tends to form smaller grains, and enhances the magnetodielectric interaction between the different phases, which indirectly benefits the magnetoelectric coupling.
