Résumé / Abstract

High coercivity film samples of the ordered Sm₂Fe₁₇N_x phase with intrinsic coercivities, _iH_c' up to 23 kOe at 293 K, and 35 kOe at 10 K, were synthesized by rf sputtering. Random orientation Sm₂Fe₁₇ films were formed by the subsequent crystallization of originally amorphous deposits. The _iH_c of the original Sm₂Fe₁₇ films was 0.75 kOe at 293 K. X-ray diffractometer traces from 2θ=28^o to 73^o, Cuna, exhibited 14 lines. Before nitriding all 14 lines were fit to the 2-17 rhombohedral structure with a=8.555 Å, c=12.445 Å, with a weighted root-mean-square deviation in 2θ of 0.01^o
