N2 - UNiAlD2.1 and UNiAlH2.3 were synthesized using a two-stage process. First, the parent intermetallic UNiAl was arc-melted from the constituent elements under Ar atmosphere, and the phase purity was verified by means of X ray diffraction. Secondly, the material was crushed and hydrogenated by means of activating the specimen in a vacuum of 10-6 Torr at 350 °C for 1 h, followed by exposure to D(H) at 55 atm pressure. The amount of absorbed D(H) was determined by monitoring the decrease of pressure in a calibrated volume. Results showed that due to lattice expansion and weakening of the 5f-ligand hybridization, UNiAlD2.1 orders magnetically at a much higher temperature than the isostructural UNiAl.
