Fe-6.5wt%Si/SrFe₁₂O₁₉ composites with different SrFe₁₂O₁₉ contents are prepared and their soft magnetic properties are investigated. SEM morphology shows that Fe-6.5wt%Si spheres are separated by SrFe₁₂O₁₉ small powders. Magnetic hysteresis loop measurement indicates that the saturation magnetization of all composites is more than 200 emu/g. Magnetic loss analysis reveals that Fe-6.5wt%Si/SrFe₁₂O₁₉ composites have excellent loss characteristics and SrFe₁₂O₁₉ can be used as insulating agent in SMCs.
