Abstract The Magnetoimpedance effect and changes of the relaxation frequency f_x are studied in CoFeSiB and CoFeMoSiB amorphous and FeCuNbSiB nanocrystalline ribbons. The evolution of the magnetostriction constant λ_s and relaxation frequency is analysed for the states with different magnetic anisotropies induced in the same ribbons. A monotonical decrease of the relaxation frequency is observed for shifting of λ_s towards positive values.
