Abstract
Amorphous ribbons of Fe78Si13B9 have been charged electrolytically wit h hydrogen. The hydrogen diffusion coefficient has been estimated by g as effusion measurements. Analysis of the change in the intensities of the Mossbauer lines of this ferromagnetic amorphous alloy of positive magnetostriction has demonstrated the effects of the hydrogen-induced compressive stresses acting in the ribbon plane. The spins are forced from their preferred in-plane alignment in an uncharged state, exhibi ting a tendency to align perpendicular to the plane in the charged sta te. The spins revert to their original alignment on effusion of the hy drogen.
