Title: Magnetic properties of Ce{sub 2}Fe{sub 17{minus}x}Al{sub x}(N{sub y}) compounds

Abstract

The authors have studied the magnetic properties of the rhombohedral Ce{sub 2}Fe{sub 17{minus}x}Al{sub x}(N{sub y}) compounds. Aluminum substitution in Ce{sub 2}Fe{sub 17} 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 Ce{sub 2}Fe{sub 17{minus}x}Al{sub x}N{sub y} can be prepared by the reaction of Ce{sub 2}Fe{sub 17{minus}x}Al{sub x} 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.
