摘要：

Magnetic properties of SmFe10(Ti, M)2 meltspun ribbons were studied, where M is V, Cr, Mn and Mo. The ribbons(H=V/Cr/Mo) quenched at 20m/s exhibit the high coercivities of 4.1-5.5 kOe. Annealing the ribbons quenched at 40m/s enhances their coercivities in the range of 5.9-10.0 kOe. In paticular, SmFe10(TiV) and SmFe10(TiCr) ribbons yield the coercivity of 10.0 kOe, and 7.9 kOe, respectively. This is the highest value among the reported melt-spun ThMn12-type structure ribbons. Importance of Sm atmosphere during annealing is also demonstrated in minimizing the Sm evaporation from ribbons. © 1990 IEEE
