摘要：

M-type barium hexaferrite (BaM) of composition BaZn0.6Sn0.6Fe10.8O19 was successfully synthesized through a ceramic process. Sintering aids Bi2O3 center dot B2O3 center dot SiO2 center dot ZnO (BBSZ) were added to lower the sintering temperature. The formation of pure M phase for samples sintered M 900 degrees C with sufficient BBSZ was confirmed from XRD patterns analysis. Large saturation magnetization (69.02 emu/g) and relatively low magnetic anisotropy field (7.4 kOe) were obtained simultaneously when sample was synthesized with 2.5 wt% BBSZ dosage. These properties make the material suitable for applications in LTCC process. The ferromagnetic resonance (FMR) linewidth (AH) decreased efficiently by 719 Oe owing to the sintering aids. This M-type hexaferrite is also potential candidate for the design of microwave devices such as circulators and isolators operated M low frequencies. Meanwhile, the influences of sintering aids upon the microstructure, complex permeability and magnetic properties of M-type hexaferrite BaZn0.6Sn0.6Fe10.8O19 were investigated.
