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.
