Abstract :
Summary form only given. Finemet composites were made by cold pressing powder with resin . The initial permeability of samples was measured by means of an impedance analyzer up to 1.8 GHz. The permeability of powder cores is usually modeled using the nonmagnetic grain boundary model (NMGB) which is improved by assuming the distribution of particles on a flat body centered-like lattice.
