LATTICE DILATION AND LOCAL MAGNETIC-ANISOTROPY IN NITROGENATED IRON-BASED SOFT-MAGNETIC FILMS

Soft magnetism in FeN-based films intimately depends on the lattice di lation caused by N incorporation. We suggest that the softest magnetic properties can be predicted in terms of critical lattice dilation. A detailed investigation of the structure constant in FeTaN films is pre sented and theoretically described. A comparison is made between Takah ashi and Shimatsu's model as function of the lattice dilation and Doyl e and Finnegan's model with respect to the film stress. Finally, predi ctions are made for the behavior of FeSiN and FeAlN films.
