Abstract
New intermetallic compounds R3Fe28Ta (R=Gd, Tb, Y) and their related hydrid es and carbides were successfully stabilised with the monoclinic structure of the Nd3Fe29-xTix type. Insertion of hydrogen and carbon atoms up to abou t 8 and 4, respectively, induce: an increase of the lattice parameters and of the Curie temperature. An analysis of the magnetisation versus the appli ed magnetic field using oriented samples was made for Tb3Fe28Ta and its hyd ride and carbide. Changes of the easy axis direction as dependent on temper ature and the nature of the inserted element were observed. (C) 2000 Elsevi er Science S.A. All rights reserved.
