Abstract

In view of the potential use of amorphous magnets as radiation-resistant materials, we performed a comparative study between laser and particle beam induced effects in amorphous alloy systems. We irradiated Fe81B13.5 Si3.5C2, Fe40Ni38Mo4B18, Fe66Co18B15Si1 and Fe72.6Cr22Al4.8Si0.3Y0.3 with pulsed laser radiation as well as with high (W=7 MeV) and low energy (W=30 and 50 keV) electrons and with 2.8 MeV alpha particles. The irradiation effects in these systems were investigated using several complementary techniques: transmission and conversion electron Mössbauer spectroscopy, magnetometry and electron microscopy. We were able to deduce details of the mechanism of magnetic texture formation and of the amorphous-to-crystalline phase transformations in the studied amorphous alloys.
