摘要：
A novel soft magnetic composites (SMCs) was prepared by Fe-6.5 wt%Si/nano-MnZn ferrites composite powders in this work. The nano-MnZn ferrites (similar to 20 nm) were synthesized by thermal decomposition method. The microstructure and electromagnetic characteristics of Fe-6.5 wt%Si/nano-MnZn ferrites SMCs were investigated in details. The results showed that the effective permeability increased firstly and then decreased with increasing nano-MnZn ferrites contents from 0 to 4 wt%. Moreover, appropriate added amounts of nano-MnZn ferrites can reduce the hysteresis losses of the SMCs. The SMCs with 2 wt% nano-MnZn ferrites and annealed at 400 degrees C have the optimum comprehensive performances with effective permeability of 142.2 (increased by 47%), total core losses of 816 mW/cm(3) (decreased by 12%) and acceptable electrical resistivity of 3.18 Omega.cm.
