Abstract

Soft magnetism in FeN-based films intimately depends on the lattice dilation 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 presented and theoretically described. A comparison is made between Takahashi and Shimatsu´s model as a function of the lattice dilation and Doyle and Finnegan´s model with respect to the film stress. Finally, predictions are made for the behavior of FeSiN and FeAlN films
