Novel ferroelectric-ferromagnetic composite material and preparation method thereof
The invention discloses a novel ferroelectric-ferromagnetic composite material and a preparation method thereof and belongs to the technical field of electronic materials. The novel ferroelectric-ferromagnetic composite material comprises a ferromagnetic phase and a ferroelectric phase, wherein the content of the ferromagnetic phase is 30-99 wt%, and the content of the ferroelectric phase is 1-70 wt%; the ferromagnetic phase is modified NiCuZn ferrite, and the main ingredients and the content of each ingredient comprise 65-68 wt% of ferric oxide, 7-10 wt% of nickel protoxide, 17-19 wt% of zinc oxide, 6-8 wt% of copper oxide, 0.5-1.5 parts of lithium carbonate and 2-4 wt% of vanadium pentoxide; the ferroelectric phase is bismuth-based perovskite ferroelectric ceramics, and the general formula is An-1Bi2BnO3n+3, wherein A is one or two of Bi, Nd, Sm and W, B is one or two of Ti and V, and n is in the range of from one to five. By means of the novel ferroelectric-ferromagnetic composite material and the preparation method thereof, under the condition that no sintering aid is needed to be added, the high densification of the material at a low temperature is achieved, the LTCC technology can be well adapted, and the loss of magnetic property and dielectric property can also be reduced to some extent.
