Název v původním jazyce

Ion bombardment of Fe-based amorphous metallic alloys

Popis výsledku v původním jazyce

Fe74Cu1Nb3Si16B6 amorphous metallic alloy is investigated after ion irradiation by 110 keV N+ and 593 MeV Au ions. The depth-profiles of the radiation damage were calculated by the SRIM2008 code. Applicability of transmission and conversion electron Mössbauer effect measurements to distinguish between the bulk and surface radiation damage is demonstrated by using different irradiation conditions. The investigated alloy is characterized by ferromagnetic interactions. The implantation does not depict appreciable changes of the samples? surfaces. Changes in chemical short-range order (SRO) are revealed in N+ irradiated alloys. Heavy Au ions caused pronounced effects in the position of the net magnetization though no impact on SRO was observed. After annealing, structural relaxation and annealingout of the irradiation-induced stresses caused the rotation of the net magnetization back to its original position.
