摘要：

The SrFe12-xSmxO19 (x = 0.1-0.5) powders were prepared by one-step chemical coprecipitation method with low-cost reagents. The structures and properties of SrFe(12-x)SmxO(19) were characterized by X-ray powder diffraction, fourier transform infrared spectroscopy, scanning electron microscopy, and vibrating sample magnetometer technique. The composites were composed of two-phase magnetic components, namely, SrFe12O19 and SmFeO3. The saturation magnetization of SrFe12-xSmxO19 (x= 0.4) was the largest, and it was 46.2 emu/g. The coercivity of the prepared composites was more than 4500 G. The synthesized composites were suitable for applications in magnetic substrate of catalysts and microwave absorbing materials.
