- γ-U metal, stabilized down to room temperature in the bcc structure by Mo doping, can absorb hydrogen at high $H_{2}$ pressures only. The product is amorphous hydride $UH_{3}Mo_{x}$ analogous to $β-UH_{3}$. Such hydrides are ferromagnetic with high Curie temperatures (up to 200 K), enhanced with respect to $β-UH_{3}$. Magnetic moment of U also increases. Large disorder together with high anisotropy lead to a very high coercivity, reaching 4 T at low temperatures. As amorphization normally tends to suppress magnetic ordering of U compounds, such hydrides represent a new class of materials, amorphous U-based ferromagnets with relatively high Curie temperature.
