Mössbauer study and magnetic properties of Fe–Si–B–Cu amorphous systems with minor substitution of carbon

Popis výsledku v původním jazyce

The effect of minor substitution of carbon on the structure and magnetic properties of Fe–Si–B–Cu-type metallic glasses was investigated. Structural investigations performed at room temperature with Mössbauer spectroscopy and X-ray diffractometry confirmed amorphous nature of the as-quenched ribbons. Average values of hyperfine magnetic fields do not significantly differ with respect to the minor changes in the metalloid contents (up to 1 at.%). No fluctuations were found in the chemical short-range order (SRO). Only structural deviations in topological SRO were revealed that were confirmed also by DSC and mTGA techniques via changes in the crystallization and Curie temperatures caused by compositional modifications. In addition, magnetic measurements show that substitution of C for Fe leads to slightly higher saturation magnetization corresponding to parallel orientation of the external magnetic field with respect to the plane of the ribbon.
