Schematic diagram of a vicinal MgO (100) substrate and orientation of various axes used in the FMR experiment and data analysis.
Angular dependence of the resonance field for various temperatures for (a) sample 1 and (b) sample 2. Solid lines are the results of fitting according to formula (1).
Temperature dependences of , fields and as determined from the fitting procedure with the use of expression (1).
Schematic diagram of an APB formed in films at the step edge on a vicinal MgO (100) substrate when the third B-layer on the lower terrace merges with the first B-layer of on upper terraces. Two cases are shown for the miscut direction of (a) and (b) crystallographic directions. The direction of step edge is marked with a dashed line. Fe–O–Fe interactions are marked with arrows in the figure for both kinds of APBs.
