摘要：

The influence of neutron irradiation on the magnetic properties of Fe80Cr2Si4B14 metallic glass is investigated by means of Fe-57 transmission Mossbauer spectroscopy and J-H hysteresis loop measurements. It is shown that the irradiation leads to a rearrangement of atoms giving rise to an increase in the average value of the hyperfine field distribution. Besides this, there are indications from both Mossbauer and hysteresis loop measurements that elastic stress centres are produced during the process of neutron irradiation as a result of atom mixing. A tendency of the mean magnetic moment to turn out of the ribbon plane as well as an increase in the coercivity force are observed. Before analysing the results of the magnetic study possible sources of radiation damage are discussed. They originate mostly from fast neutrons and high energy alpha and lithium particles.
