  • Abstract
    We have studied the magnetic properties of the rhombohedral Ce2Fe17-xAlx(Ny) compounds. Aluminum substitution in Ce2Fe17 leads to ferromagnetism for medium Al concentration and to cluster glasses for high Al concentration. The Curie temperature shows a maximum. Rare-earth nitrides of the composition Ce2Fe17-xAlxNy can be prepared by the reaction of Ce2Fe17-xAlxNy with nitrogen gas at 500°C. The crystal structure and lattice constants have been determined for all compounds. The Curie temperature enhances upon nitrogenation. The nitrogen absorption capacity decreases with composition x and vanishes for x>5. The enhancement of the Curie temperature of the nitrides decreases according to the absorption capacity
