Název v původním jazyce

Ion irradiation induced structural modifications of Fe81Mo8Cu1B10 NANOPERM-type alloy

Popis výsledku v původním jazyce

Structural modifications and their impact upon magnetic properties are studied in amorphous NANOPERM-type 57Fe81Mo10Cu1B10 metallic glass exposed to irradiation with 130 keV N+ ions to the total fluencies of up to 2.5x1017 ions/cm2. Using surface sensitive technique of Mössbauer spectrometry, traces of crystalline phases are found already in the as-quenched state after the sample production. On the air side of the ribbons, bcc-Fe domi-nates whereas on the opposite wheel side, also a presence of Fe3O4 is unveiled. The amount of surface crystalliza-tion is higher on the wheel side of the ribbons. After ion irradiation, mostly the air side is affected because it was facing the incident ions. Gradual formation of iron ni-trides is observed with increasing ion fluence. Though the radiation damage exhibits itself only at this side of the ribbons, its influence upon bulk magnetic properties is clearly identified by the help of magnetic measure-ments. Hysteresis loops exhibit changes in their shape as well as coercive field. Along with the formation of mag-netic crystalline phases (bcc-Fe and nitrides), they are caused by structural rearrangement which takes place also inside the amorphous residual phase. Structural modifications are confirmed via evolution of hyperfine magnetic fields with ion fluence.
