Abstract
In this paper some structural and chemical informations about the comp ound A1 are given. Transmission electron microscopy investigations rev eal that it is composed of a mixture of two nanocrystalline compounds A1 alpha and A1 beta, with atomic compositions close to Nd20Fe80 and N d40Fe60 respectively. Their formation is described in a metastable pha se diagram including also NdFe2, and is confirmed by thermodynamic cal culations on the basis of Miedema's model.
