文摘

Fe-Cr-Co-type ribbons were prepared by melt spinning combined with heat treatment. The coercivity as high as 742 Oe can be achieved. The microstructure and domain structure changes during heat treatment were investigated. Magnetization process is observed by Lortenz transmission electron microscopy. The models of phase transition and coercivity mechanism are built up.
