| Popis: | Impact of the wheel speed upon microstructure and hyperfine interactions of amorphous Fe78Si9B13 ribbons was studied. Mossbauer spectrometry, differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, atomic force microscopy, and magnetic measurements were applied. Though minor effects of wheel speed upon macroscopic magnetic properties was found, notable changes in repositioning of magnetic moments of the resonant atoms caused by modifications in the topological short-range order (SRO) were unveiled. No deviations were observed in the chemical SRO. The observed effects were enhanced after annealing at moderate temperatures. |
