Abstract
Induction melted GdFe11-xSixTi alloys (x less than or equal to2) with ThMn1 2-type structure have been investigated. The decrease of Curie temperature, magnetic moment and anisotropy constant are ruled by Si 3p electron transf er into Fe 3d band. The increase of the exchange interaction parameter betw een Gd and Fe sublattice shows that indirect 3d-4f interaction is enhanced. (C) 2001 Elsevier Science B.V. All rights reserved.
