Abstract

DC magnetron sputtering has been used to fabricate SmFe12 films with ThMn12 type of tetragonal structure. SmFe12Nx films were made by heating the sample in situ in a low pressure nitrogen atmosphere. The lattice parameters are a = 8.589 Å, C = 4.807 Å for SmFe12 films and a = 8.735 Å, c = 4.895 Å for SmFe12Nx films respectively, corr esponding to a volume increase of about 5.3% upon nitrogenation. A change of anisotropy and an increase of Curie temperature upon nitrogenation are observed. Aspects of crystal structure, texture and magnetic properties are reported.
