A conversion electron Mossbauer spectroscopic study of structural relaxations and diffusive transport near the surface of Fe₆₇Co₁₈B₁₄Si₁metglass

Abstract

Structural relaxations and diffusive transport near the surface of Fe₆₇Co₁₈B₁₄Si₁ metglass have been studied by means of conversion electron Mossbauer spectroscopy [CEMS]. It is shown that the relaxations occurring near the surface of the metglass consequent on thermal treatment exhibit distinctly different features as compared to those in the bulk. The difference in the thermally induced atomic transport near the surface region of the metglass and, that at the interface between the metglass and a deposited overlayer of iron has also been investigated.
