Abstract

γ-U alloys with Mo or Zr are more resistant to hydrogen than U metal. High pressures of H are needed to produce hydrides. Amorphous structure of UH3Mox can be represented as the cubic structure of β-UH3 type with grain size around 1 nm. UH3Zrx are formed in the cubic α-UH3 type of structure. All the hydrides are ferromagnets, with magnetic parameters (magnetic moments, Curie temperature) exceeding those of β-UH3 (0.9 μB/U, 165-170 K). It is deduced that α-UH3 has magnetic properties very similar to β-UH3, despite rather different U-U spacing.
