Atomic structure analysis of NdFe and NdCo amorphous films

Abstract

The amorphous structures of Nd17Fe83 and Nd18Co82 alloys with high Kerr rotation at short wavelengths were examined by means of X-ray diffraction, using dense random packing of hard sphere model analysis and polyhedron analysis. It was observed that the general local environments of NdFe and NdCo amorphous structures are very similar and that their local atomic structures are very close to those of an RETM2 crystalline Laves phase. © 1994.
