Structural relaxation, crystallisation and optimisation processes in soft magnetic amorphous alloys based on iron are examined by applying different experimental techniques: X-ray diffraction analysis, high-resolution electron microscopy, measurements of magnetic and electric properties (permeability, after-effect, resistivity). The presented results are discussed in terms of annealing out of microvoids, formation of a nanocrystalline phase and changes of effective magnetostriction constant.
