RESEARCH
Experimental studies of electronic and atomic structure of metallic amorphous and nanocrystalline solids

MAIN ISSUES
1. Electron transport processes in amorphous and nanocrystalline alloys.
2. Electronic, atomic and magnetic structures in amorphous and nanocrystalline solids.
3. Mechanisms and kinetics of nanocrystallization.

EXPERIMENTAL TECHNIQUES
Electron transport processes are studied by the electrical resistivity and thermoelectric power measurements between 100 and 1200 K.
The mechanisms and kinetics of nanocrystallization are analysed using synchrotron methods like X-ray diffraction (XRD) and simultaneous small- and wide-angle X- ray scattering (SAXS/WAXS).
The glass structure is investigated by X-ray absorption fine structure spectroscopy (XAFS). The amorphous alloys studied are prepared by a rapid quenching from a liquid phase, including the Al based nonmagnetic and the magnetic ones based on Fe, Co and Ni.
