Abstract
Magnetic disorder in neutron-irradiated (fission fragment damage) uranium mononitride (UN) has been investigated by magnetic susceptibility measurements. The Néel point (TN ) shifted to lower temperatures with increasing fission dose and attained the lowest value at a dose of around 1018 f/cm3. After further irradiations, however, it recovered to the non-irradiated value. The shift of TN was in accordance with the change of the concentration of fission-induced vacancies. Other magnetic parameters showed a similar trend. These fission-fragment damage results are discussed in terms of the electronic state of 5 f electrons.Keywords
