High coercivity in Sm(FeT)/sub 12/ type magnets

The magnetic properties and microstructure of melt-spun iron-rich ternary alloys with the ThMn/sub 12/-type structure are reported. Rapidly quenched samples were prepared with composition Sm/sub x/Fe/sub y/T/sub z/, where T=Ti, V, Mo, Cu, Al, Si or a mixture of these, and 86.5 kOe.
