High coercivity in Sm5Fe17 melt-spun ribbon

Sm-Fe binary alloy with the hard magnetic Sm5Fe17 phase was produced by melt-spinning followed by heat treatment. The magnetic properties of the Sm-Fe melt-spun ribbon depended on the annealing temperature. The highest coercivity, iHc=1.90MAm-1, was obtained by annealing the Sm-Fe melt-spun ribbon f...

Beschreibung
Zusammenfassung:	Sm-Fe binary alloy with the hard magnetic Sm5Fe17 phase was produced by melt-spinning followed by heat treatment. The magnetic properties of the Sm-Fe melt-spun ribbon depended on the annealing temperature. The highest coercivity, iHc=1.90MAm-1, was obtained by annealing the Sm-Fe melt-spun ribbon for 1h at 923K. The coercivity of the Sm5Fe17 melt-spun ribbon was attributed to the grain size of the hard magnetic Sm5Fe17 phase.
