Abstract

The relationship between coercivity (H_c) and magnetostriction (λ_s) of the glassy Fe-(Al, Ga)-(P, C, B, Si) alloys has been discussed. The glassy Fe-(Al, Ga)-(P, C, B, Si) alloys exhibit lower H_c and lower I_s compared with the conventional Fe-based amorphous alloys with the same λ_s and Fe content, respectively. Theoretical analysis on the basis of domain-wall movement suggests that the low H_c results from the long-range homogeneous structure of the glassy alloys, which realizes a low density of pinning centers. The good combination of high glass-forming ability and good soft magnetic properties (especially low H_c) indicates the possibility of future development as new bulk glassy soft magnetic materials.
