Crystal Chemistry and Physics of UCd(11)

[Image: see text] In the phase diagram U-Cd, only one compound has been identified so far—UCd(11) (space group Pm3̅m). Since the discovery of this material, the physical properties of UCd(11) have attracted a considerable amount of attention. In particular, its complex magnetic phase diagram—as a result of tuning with magnetic field or pressure—is not well-understood. From a chemical perspective, a range of lattice parameter values have been reported, suggesting a possibility of a considerable homogeneity range, i.e., UCd(11–x). In this work, we perform a simultaneous study of crystallographic features coupled with measurements of physical properties. This work sheds light on the delicate relationship between the intrinsic crystal chemistry and magnetic properties of UCd(11).
