Nd(Fe,Ti)[sub 12] and Nd(Fe,Ti)[sub 12]N[sub [ital x]] films textured with [ital c] axis perpendicular to the film plane were synthesized by sputtering. For the Nd(Fe,Ti)[sub 12] films a spin reorientation took place at about 170 K. For the Nd(Fe,Ti)[sub 12]N[sub [ital x]] films, the anisotropy field is about 85 kOe at room temperature and 130 kOe at 5 K, corresponding to a coercivity of 2.7 and 12 kOe, respectively. Initial magnetization curves show a behavior characteristic of nucleation type of magnetization reversal mechanism. Attempts were made to fit the experimental data with Kronmueller's magnetization reversal model. The results suggest that nucleation with extended sites is responsible for the reversal.
