Abstract

The influence of electrolytic hydrogenation on the magnetic properties of three different kinds of amorphous alloys has been investigated. The alloys studied were Fe_83.3Si_3.5B _11.2C₂, Fe₃₈Ni₃₈Mo₂Si₈B₁₄, and (Co₈₆Fe₅Cr ₉)₇₅Si₁₀B₁₅. The experimental results showed that after hydrogenation the samples became very brittle and the soft magnetic properties degraded dramatically, but saturation magnetization σ_s and average hyperfine field increased markedly. As hydrogen evolved from the charged samples which were placed in air at room temperature, the magnetic properties, toughness, and average hyperfine field were gradually recovered
