The as-cast wires were amorphous. The annealed wires exhibited an ultra-fine structure with a grain size of 10-12 nm. A strong inhomogeneity of the near-surface magnetic properties of the as-cast samples was found. This was explained by the dispersion of the magnetic anisotropy, which is a typical phenomenon for as-cast amorphous materials. Nanocrystalline phase formation in the annealed wires was found to lead to an improvement in their soft magnetic properties and a significant increase in the homogeneity of the magnetic characteristics. The magnetic field behaviour of the near-surface magnetization components allows us to conclude that there is a curling mode of the magnetization reversal in the examined microwires.
