Several diverse types of UH3-based hydrides can be prepared by hydrogenation of bcc Ubased alloys. Pair Distribution Function (PDF) analysis using high-energy X-rays identified that the (UH3)1-xMox hydrides are nanocrystalline, with the structure motif based mainly on the alpha- UH3 structure. alpha-UH3 represents a minority component.
On the other hand, PDF of the (UH3)1-xZrx hydrides corresponds well to the alpha-UH3 crystal structure. All the hydrides are ferromagnetic, with the Curie temperature TC reaching up to 203 K.
