%X A series of composites were synthesized by solida2state reaction, with ferroelectric powder of BST and ferromagnetic powder of YIG as raw materials. Dielectric and magnetic properties of ferroelectrica2ferromagnetic composites were tested. The results show that the ferroelectric/ferromagnetic composites sintered at proper temperature consist of ferroelectric phase and ferromagnetic phase. The composite materials xBST-(1-x)YIG(x=0￡ 0.1￡ 0.2￡ 0.3￡ 0.4￡ 0.5￡ 0.6￡ 0.7￡ 0.8￡ 0.9￡ 1.0) exhibit excellent dielectric and magnetic properties. Both |  nd |  ncrease with the increase of BST content, and the dielectric resonant frequency shifts to a higher frequency with YIG content increasing. The permeability rises with BST content decreasing. The resonance frequency and high frequency characteristics of YIG are improved by adding BST.
