Abstract

We describe basic magnetic properties of uranium-based hydrides UTi₂H_x, reported in literature as a cubic Laves phase, although the UTi₂ binary phase does not exist. Using a high-temperature hydrogenation, we successfully synthesized two types of such hydrides, presumably with different H concentrations, one with a smaller lattice parameter a = 850.3 pm, which is a paramagnet close to the verge of magnetic ordering, the other with a = 858.8 pm, with a ferromagnetic ground state and ordering temperature T_C = 54 K.
