Název v původním jazyce

Changes in the hyperfine interactions in the Fe80Nb3Cu1B16 metallic glass under tensile loading

Popis výsledku v původním jazyce

The influence of tensile stress on the changes in hyperfine parameters obtained by Mössbauer spectroscopy of the ferromagnetic amorphous NANOPERM-type Fe80Nb3Cu1B16 alloy has been investigated. The bulk changes are obtained by Mössbauer spectroscopy in atransmission geometry using ?-rays; the surface properties are studied in a scattering geometry using conversion electrons. The Mössbauer spectra are analyzed by two distributions of hyperfine inductions which result in high-field and low-field components corresponding with a model of clusters formed by predominantly iron atoms and intermediate phase containing mainly the Nb, Cu and B atoms. The obtained results are completed by the bulk and surface magnetic measurements, with observations of the surface morphology by AFM and microstructure by SEM. The investigations yield approximately linear increase of hyperfine parameters and slight deterioration of the bulk as well as surface magnetic characteristics with tensile loading.
