ON THE SITE PREFERENCE OF 3D ATOMS IN COMPOUNDS OF THE R2(CO1-XFEX)14B TYPE

This study reports the results of **5**7Fe Moessbauer spectroscopy performed on Nd//2Co//1//4B doped with **5**7Fe. The compound Nd//2Co//1//4B is isotypic with Nd//2Fe//1//4B, both compounds forming the boundaries of a series of solid solutions, in which the Curie temperature increases continuously with cobalt content. The purpose of this study was to determine whether cobalt and iron atoms occupy the six crystallographically nonequivalent transition metal sites at rangom or whether iron atoms occupy one or more of these sites preferentially. 11 refs.
