on the microstructure of the sample. The application of nanocrystalline soft magnetic materials in high-frequency range requires the optimization of their dynamic properties such as the complex permeability[1]. Factors affecting the complex permeability have been received great attention. The influences of B content and magnetic field annealing on the soft magnetic properties of Fe-M-B nanocrystalline......
