Abstract
In-situ grazing incidence X-ray diffraction was used to measure the la ttice parameter as a function of thickness for epitaxial Fe (110) film s on Mo (110). A large, thickness-dependent, anisotropic in-plane stra in was observed. This strain behavior is explained with an equilibrium misfit dislocation model incorporating anisotropic elasticity. The ma gnetostrictive anisotropy expected from this strain has nearly linear behavior in reciprocal film thickness and thus could be mistaken for a surface anisotropy.
