Abstract
The compositional distribution in a Co78Cr22 film grown epitaxially on Ru/mica by electron beam evaporation was investigated using spin-echo Co-59 nuclear magnetic resonance (NMR) and preferential chemical etch ing of Co. NMR revealed evidence for the occurrence of drastic composi tional separation producing a Go-enriched component containing almost pure Co. Chemical etching revealed a particularly fine distribution of Go-enriched regions. These results are consistent with the propositio n that the enhanced saturation magnetisation (M(s)) observed in these films is attributable to enhanced compositional inhomogeneities.
