Changes in the Surroundings of the Central Iron Atom in Amorphous Alloys

Abstract

Amorphous alloys are still a challenge for science when it comes to an accurate description of their structure and magnetic properties. There are many techniques for studying the structure, however, the direct observation of the amorphous structure does not bring much to the description of the phenomena occurring in them. In the case of ferromagnetic amorphous alloys, their properties can be studied based on the analysis of transmission Mössbauer spectra and the hyperfine field induction distributions obtained on their basis. The work investigated the influence of changing the surroundings of the central iron atom on the magnetic properties of a soft magnetic amorphous alloy. Samples after solidification and after isothermal annealing at a temperature below the crystallization temperature were tested.
