Abstract

A series of composites were synthesized by solidstate reaction, with ferroelectric powder of BST and ferromagnetic powder of YIG as raw materials. Dielectric and magnetic properties of ferroelectricferromagnetic 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 ε′ and ε″ increase 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.
