Abstract

The results of composition and phase analysis for SmFe11Ti melt-spun ribbons annealed in vacuum have revealed that α-(Fe, Ti) phase with low coercivity exists mainly on the ribbon surface. Removal of surface low coercivity layers of ribbon by chemical etching is found to be effective in increasing the coercivity. A coercivity of 565 kA/m (7.1 kOe) is obtained by the surface etching of a SmFe11Ti melt-spun ribbon. This value is about 35% higher than that of the ribbon before the etching.
