Metallic glass ribbons of composition Fe₈₃(Sn/P)₅B₁₂ with or without 2% phosphorus substitution were irradiated with a 5 MeV electron beam, and 4 MGy dose. We examined the effect of irradiation on magnetic properties in amorphous sample, and its result in nanocrystallized sample. Both irradiated and non-irradiated samples were annealed at 400° for 1/2 h in vacuum to obtain the nanocrystalline phase. The P-containing ribbon is better in terms of magnetic softness but the saturation induction is reduced by 2.5%. Both the materials show merely minute effects of the irradiation after nanocrystallization.
