“…They are potential alternatives to the 'classical' compositions of nanocrystalline alloys like NANOPERM, HITPERM, or even NANOMET and can ensure the sustainability of soft amorphous magnetic material production at reasonable costs. Moreover, the studied Fe(Co)-B-Sn MGs exhibit a nanocrystalline structure after appropriate heat treatment [17], which ultimately leads to the desired soft magnetic properties.…”

“…It dissolves in solid Fe(Sn) with difficulty and forms practically no solid solution with boron. Recently, the effects of Cu and Co additions on Fe-Sn-B-based MGs were investigated [15][16][17][18]. The influence of Sn on the glass forming ability and magnetic properties of Fe-B-P-Sn amorphous alloys with a high Fe content was also reported [19].…”

Fe78B15Sn7 and (Fe3Co1)78B15Sn7 amorphous metallic alloys were prepared using the method of planar flow casting. The amorphous nature of ribbons containing 7 at. % Sn was verified by X-ray diffraction. The resulting chemical composition was checked by flame atomic absorption spectroscopy and by mass spectrometry with inductively coupled plasma. The microstructure of the as-quenched metallic glasses was investigated by 57-Fe and 119-Sn Mössbauer spectrometry. The experiments were performed with transmission geometry at 300 K, 100 K, and 4.2 K, and in an external magnetic field of 6 T. The replacement of a quarter of the Fe by Co did not cause significant modifications of the hyperfine interactions in the 57-Fe nuclei. The observed minor variations in the local magnetic microstructure were attributed to alterations in the topological short-range order. However, the in-field 57-Fe Mössbauer spectra indicated a misalignment of the partial magnetic moments. On the other hand, the presence of Co considerably affected the local magnetic microstructure of the 119-Sn nuclei. This was probably due to the higher magnetic moment of Co, which induces transfer fields and polarization effects on the diamagnetic Sn atoms.
