Opis:: The magnetization processes in region of small excitation magnetic fields - Rayleigh region, were investigated on the amorphous and nanocrystalline FINEMET ribbons. The significant differences in behaviour of these materials were found. This could be explained by the difference in the value of magnetoelastic anisotropy as well as by the different thickness of the domain walls in these materials.

Opis:: In this contribution a less common experimental procedure is presented, which includes simultaneous application of electrical pulse heating, and longitudinal mechanical stress, applied along the ribbon length, for the magnetic property tailoring. The annealing is performed in protecting atmosphere in a vertical tube furnace by applying a weight at the free, cold bottom end of the ribbon. In these circumstances neither nanometer-size grains nor the concentration-distribution have been developed. The static coercive force, anisotropy and demagnetizing factor are monitored as a function of pulse number.

The structural changes were connected with the temperature range where the Fe$\text{}_{80}$V$\text{}_{5}$B$\text{}_{15}$ amorphous alloy was characterized by the soft magnetic properties.

Opis:: The magnetization processes in amorphous and nanocrystalline FINEMET ribbons were studied by the numerical decomposition of the quasi-static hysteresis loop to the contributions of the domain wall movement, the domain rotations, and the domain wall annihilation and nucleation processes following the hyperbolic T(x) model of hysteresis. The hysteresis data measured during decrease of the excitation magnetic field were used for the separation of these processes. The significant differences in behavior of these two materials were found. In amorphous state the domain rotations component dominates whereas in nanocrystalline state the domain wall movement component prevails. These differences are reflected in the anisotropy field distributions as well.
