摘要：
We have studied the magnetic properties of the rhombohedral Ce2Fe17-xAlx(Ny) compounds. Aluminium 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 composition Ce2Fe17-xAlxNy can be prepared by the reaction of Ce2Fe17-xAlx with nitrogen gas at 500-degrees-C. The crystal structure and lattice constants have been determined for all compounds. The Curie temperature becomes enhanced 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 along with the reduced absorption capacity.
