Abstracts

EN

Formation of the soft magnetic nanostructure in amorphous Fe_{41}Ni_{40}Zr_7B_{12} alloy due to heat treatment is studied by the Mössbauer, differential scanning calorimetry, and X-ray diffraction techniques. Annealing at temperatures 520-580ºC leads to the formation of extremely soft nanocrystalline alloy as revealed by the rf-Mössbauer measurements. The superparamagnetic behaviour was observed for the alloy annealed at 620-640ºC. At higher annealing temperatures good soft magnetic properties deteriorate.
