Influence of structural transformations on functional properties of Fe75Ni2Si8B13C2 amorphous alloy

Popis výsledku v původním jazyce

The influence of thermal treatment on functional properties of Fe75Ni2Si8B13C2 amorphous alloy was investigated. Thermal history of the sample was found to have a significant effect on magnetic properties. Structural transformations were identified usingDSC and thermomagnetic curve and characterized using Mössbauer spectroscopy and X-ray diffraction. Further investigation of magnetic and electrical properties of the alloy showed that structural relaxation prior to crystallization affected both magneticsusceptibility and electrical resistivity of the alloy, leading to an increase in both. This was caused by a confluence of stress relieving and a decrease in number of defects and an increase in free volume in the alloy sample, not only enabling greatermobility of magnetic domain walls, but also decreasing electron density of states at the Fermi level. The alloy also exhibits a wide supercooled liquid region before crystallization, where its functional properties remained relatively co
