Abstract
Results are presented of a magnetooptic investigation of the surface micromagnetic structure of FeCuNbSiB ribbons in the initial state and after annealing at 550 °C for 1 h. In the initial state the samples were amorphous, whereas after annealing they exhibited a nanocrystalline structure with typical grain sizes of 10–12 nm. Dispersion of the magnetic anisotropy was observed in the samples studied; this was responsible for the nonuniformity of their local magnetic properties. It was found that the linear dimension of the magnetic inhomogeneities in the initial and annealed samples was 120–150 and 50–70 μm, respectively.
