According to a study from Prague, Czech Republic, "The effect of hydrogenation on magnetic properties of the weakly ferromagnetic superconductor UCoGe was studied. UCoGe hydrides were synthesized at T = 773 K at different pressure of H-2 gas (8, 5, 2 bar)."
"The hydrogenation at 8 bar and 5 bar results in a chancre of the crystal structure from orthorhombic (TiNiSi structure type) to hexagonal (ZrBeSi type) with H concentrations just below 2 H/f.u. For one of such beta-hydrides, UCoGeH1.7, the Curie temperature increases from 3 K up to 50 K and the spontaneous magnetic moment from 0.03 mu(B)/f.u. to 0.05 mu(B)/f.u. An a-hydride of UCoGe (Delta V/V=0.25%) with a ...
