The effect of the B2 O3 flux melting; which improves the glass-forming ability of bulk metallic glasses (BMGs); on the soft magnetic properties of the cast [(Fe0.5 Co0.5)0.75 B0.20 Si0.05] 96 Nb4 BMG has been investigated. The ring-shaped bulk specimens prepared by the B2 O3 flux melting and copper mold casting exhibit the better soft magnetic properties than those of the ones prepared by the conventional copper mold casting. It probably originates for eliminating the nonmetallic inclusions which behave the pinning sites of magnetic domain walls by the B2 O3 flux melting. The B2 O3 flux melting is effective for improvement of the soft magnetic properties of BMGs. © 2008 American Institute of Physics;
