| Research Abstract |
Sm_xFe_<73.5_<-x>>Cu_1Nb_3Si_<15.5>B_7 amorphous ribbons(x = 0 - 10) were prepared by the single roll method, and then the ribbons were annealed. Although obtained results suggest the existence of Sm-Fe compound phase, we could not obtain the ribbons with good soft magnetic properties. In order to improve the soft magnetic properties of the ribbon, we applied a pulse annealing method to the amorphous ribbons. We confirmed the SmFe_2 phase in the pulse-annealed Sm_2Fe_<71.5>Cu_1Nb_3Si_<15.5>B_7 ribbons. Homogenizing for the annealed-state of the ribbon is one of the important tasks for the preparation of the core with excellent soft magnetic properties.
