In this article, one of the production method of Fe based amorphous metallic materials, exhibiting excellent soft magnetic properties was described. The presented method consists in the unidirectional casting of the liquid alloy on to rotating, at high frequency, copper wheel. The produced samples had a ribbon shape with a thickness of about 45 microns. Apply this method allows to obtain materials exhibiting the lack of long-range ordering between the atoms and characterized by unique magnetic and mechanical properties. The structure of produced samples was investigated using Mössbauer spectroscopy and X-ray diffraction. The saturation magnetization [...] and coercivity field (Hc) of ribbons in the as-cast state, have values corresponding to materials, with good soft ferromagnetic properties. On the basis of structural and magnetic investigations, it was found that the obtained samples were amorphous and had very good magnetic properties. That allows us to think, that the presented method makes it possible to fabricate the amorphous materials, characterized by the good electrotechnical parameters.
