TL;DRAbstract

Great attention has been paid to the RFe_(11)(Ti, V) compounds with ThMn_(12) type structure since 1987. Among them the SmFe_(11)Ti compound seems to be the most promising candidate for permanent magnets(PMs). However, the saturation magnetization of SmFe_(11)Ti is much less than that of Nd_2Fe_(14)B although its Curie temperature T_C is approximately the same as that of Nd_2Fe_(14)B; in addition, Sm is more expensive than Nd. All this makes SmFe_(11)Ti uncompetitive from economic point of view.
