(a) Evolution of the lateral (crosses) and vertical (circles) layer distances for different Ni contents, determined by fitting of (113)NFO for films with an Ni content up to x = 1. The layer parameters for the overstoichiometric films (x > 1) were taken from the interpolation of the (222)NFO Laue fringes. (b) The lateral and vertical layer distances for different Ni contents at a film thickness of df = 8.25 (7) nm. The expected bulk values for FeO, MgO, Fe3O4, NiFe2O4 and NiO at the deposition temperature of 523 K are indicated by dashed lines. |
