摘要：

In this research, Fe-Si-B/carbonyl iron soft magnetic composites were prepared with the aim of having low magnetic loss and temperature-dependent characteristics. An increase in the carbonyl iron powder content resulted in an increase of saturation magnetization intensity in the Fe-Si-B/carbonyl iron hybrid powder. The presence of carbonyl iron particles improved the coupling between the Fe-Si-B particles, reducing iron loss and enhancing the magnetic permeability of the soft magnetic composites, resulting in excellent magnetic properties even at high frequencies and temperatures. However, when the content of carbonyl iron powder surpassed 25% and reached 40%, its effect on the magnetic performance of the soft magnetic composites decreased.
