The Y3Fe5O12(YIG ) and Y1.05Bi0.75Ca1.2Fe4.4V0.6O12(YBiCaVIG) ferrites doped with different ZnO B2O3 SiO2 (ZBS) glass contents has been prepared by the common ceramics method.The phase composition,microstructure and magnetic properties of the samples were investigated. It was found that ZBS glasscould effectively decrease the sintering temperature of YIG and YBiCaVIG ceramics.When the doping content of ZBS was w(ZBS)=10%,the sintering temperature of YIG and YBiCaVIG ceramics could be reduced to 1 280 ℃ and 950 ℃ respectively.But the XRD patterns showed that a few SiO2 and YFeO3(YIP) impurities were formed,meanwhile,the SEM showed that the samples have the grain size of about 2~4 μm and higher pores rate.After doping ZBS glass,the saturation magnetizations 4πMs decreased while the ferromagnetic resonance line width ΔH increased. However, since the samples have bigger spin wave line width ΔHk and smaller grain size,they are suitable for large power YIG materials.
