摘要：

The hard magnetic properties of melt-spun Sm2Fe15Si2C were studied. A coercivity of mu(0i)H(c), = 0.84 T and an energy product of 60 kJ m(-3) at room temperature were obtained for a sample prepared at a wheel speed of 20 m s(-1); correspondingly, the size of crystalline grains in these samples is about 38 nm. The mechanism of coercivity is mainly controlled by the nucleation of reversed domains. The phenomenon of remanence enhancement was observed in the melt-spun Sm2Fe15Si2C.
