采用溶胶-凝胶法制备了BaFe(9)(Mn(0.5)C(0.5)Sn)(3/2)O(19)。用X射线衍射仪、透射电子显微镜、交流磁化率计、振动样品磁强计和矢量网络分析仪对样品的结构、静态和动态磁性能进行了分析。制备的铁氧体颗粒呈不规则非球形，尺寸分布较宽。取代对降低材料的矫顽场是非常有效的。根据微波反射率的测量，BaFe(9)(Mn(0.5)C(0.5)Sn)(3/2)O(19)是一种很好的高频电磁兼容性和其他实际应用的候选材料。
Substituted barium ferrite BaFe(9)(Mn(0.5)C(0.5)Sn)(3/2)O(19) was prepared by sol-gel method. X-ray diffraction (XRD), transmission electron microscope (TEM), AC susceptometer, vibrating sample magnetometer (VSM) and vector network analyzer were used to analyze the structure, static and dynamic magnetic properties of the prepared samples. The prepared ferrite particles possess irregular non spherical shape with a broad size distribution. The substitution was very effective in reducing coercive field of the material. Based on microwave measurements of reflectivity, BaFe(9)(Mn(0.5)C(0.5)Sn)(3/2)O(19) is a good candidate for electromagnetic compatibility and other practical applications at high frequencies.
