The structure and magnetic properties of Sm{sub 3}(Fe{sub 0.85}Cr{sub 0.15}){sub 29}N{sub y} alloy were investigated. It was found that the alloy had the R{sub 3}(Fe,M){sub 29}-type structure and absorbed 4--5 wt.% of nitrogen which exceeds 4 nitrogen atoms per unit formula. The coercivity of the powder was greatly influenced by the nitrogen content and annealing. The Sm{sub 3}(Fe{sub 0.85}Cr{sub 0.15}){sub 29}N{sub y} alloy powder with 4.1 wt.% of nitrogen showed a high coercivity of 552 kA/m without fine grinding.
