| Research Abstract |
The glassy/crystalline composite soft magnetic material with a structure composed of crystalline phases whose size of 50. 100. m in diameter embedded in a glassy phase has been developed. The composite material whose chemical composition is(Fe_<0. 75> B_<0. 20> Si_<0. 05>)_<96> Nb_<4> could be prepared by B_2O_3 flux melting and copper mold casting, and has a flat hysteresis curve ; i. e., there is a good linear relationship between magnetic induction and magnetic field because the magnetic domain wall displacements are pinned by the precipitated crystalline phases. This composite material is useful for the energy saving of magnetic components such as the choke coils.
