Preparing method for multilayer magnetoelectric composite material

A preparing method for a multilayer magnetoelectric composite material relates to a magnetoelectric composite material. The preparing method comprises the steps of cutting required metal raw materials into a plurality of layers of ferromagnetic phases with interdigital electrode structures, cleaning and drying the ferromagnetic phases, choosing and mixing three parts of A components and one part of B components in epoxy resin, standing and defoaming the three parts of A components and one part of B components in epoxy resin to obtain epoxy resin AB mixture, adding piezoelectric ceramic powder, mixing, standing and defoaming the epoxy resin AB mixture to obtain a piezoelectric phase prefabricated body with the fluidity, placing the layers of the ferromagnetic phase structures into a mould, filling the piezoelectric phase prefabricated body with the fluidity to fully fill up interlayer spacing of the ferromagnetic phases, flowing out of the lower surfaces of the ferromagnetic phase structures, standing to solid
