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.

采用单辊法制备了Sm_xFe_<73.5_<-x>>Cu_1Nb_3Si_<15.5>B_7非晶带（x = 0 ~ 10），并对其进行了退火处理。虽然得到的结果表明Sm-Fe复合相的存在，但我们无法得到具有良好软磁性能的条带。为了提高非晶带的软磁性能，我们对非晶带进行了脉冲退火处理。我们在脉冲退火的Sm_2Fe_<71.5>Cu_1Nb_3Si_<15.5>B_7条带中证实了SmFe_2相。对带的退火态进行均匀化是制备软磁性能优异的磁芯的重要工作之一。
