Opis:: Temperature studies in the range 300 800 K of amorphous Fe80Nb6B14 alloy using Mössbauer spectroscopy are presented. It is shown that at a temperature close to 700 K iron clusters with non-collinear magnetic structure are formed. The observed magnetic permeability enhancement effect in the annealed at elevated temperatures alloy, which takes place in amorphous phase, is due to the strong ferromagnetic exchange between Fe clusters via the amorphous matrix and reduction of internal stresses.

Opis:: Experimental results of irradiation effects by heavy ions with high inelastic energy losses at the surfaces of some amorphous alloys are presented. It was shown that all studied alloys strongly swelled: up to 15% for Ni58Nb42 under irradiation with the 305 MeV 86Kr ion at a fluence of 1015 ion/cm2. Besides, the sputtering (evaporation) process takes place, too. Calculations of the temperatures on the ion trajectory axis were presented. It was shown that the calculated temperatures are higher than the melting temperature and the evaporation temperature, too. From these findings we can conclude that the sputtering (evaporation) of atoms in amorphous alloys is present.

Opis:: Microstructure and thermomagnetic characteristics of the amorphous Fe51Co12Si16B8Mo5P8 alloy in the as-quenched state and after 1 h of annealing at 573 K and 773 K are studied. The structural investigations performed by Mössbauer spectroscopy and X-ray diffractometry confirmed the amorphous structure of the analysed materials. An increase in the annealing temperature up to 773 K does not lead to crystallization of the amorphous alloy. Only structural rearrangement that causes changes in the topological short-range order and annealing out of free volume is observed. This behaviour was confi rmed by modifications of the shapes of hyperfi ne field distributions derived from the corresponding Mössbauer spectra of the investigated alloys. The Curie temperatures of the as-quenched and annealed Fe51Co12Si16B8Mo5P8 alloy at 573 and 773 K are 400, 405 and 421 K, respectively.

Opis:: Thermal treatment, undertaken at just below the crystallization temperature, has led to nanocrystallization and has had a signifi cant impact on the shape of the hyperfine field induction distributions of Fe62Co10Y8B20 alloy and on its soft magnetic properties. In the amorphous ferromagnetic alloys, it is possible to indirectly determine the effect of the structure stresses, resulting from the presence of structural defects, on the soft magnetic properties of these materials. It has been found that a change in the parameters associated with the presence of structural defects affects the shape of the hyperfi ne fi eld distributions of 57Fe.
