Summary: FeSiCr soft magnetic composites (SMCs) with yttrium iron garnet (YIG) coating layer were studied. It was found that a moderate amount of YIG ferrite could form a thin and uniform layer, resulting in significant optimizations in core loss, permeability, and DC bias characteristics. The FeSiCr/YIG SMCs with 0.75 wt% YIG exhibited the best magnetic performance and the lowest core loss and largest permeability at the optimal annealing temperature of 500 degrees C. This study provides potential applications of FeSiCr/YIG SMCs in high-frequency fields.
