On crystal chemistry of a well-known uranium-based antiferromagnet

November 29, 2022

In the phase diagram U-Cd, only one compound has been identified so far-UCd11 (space group Pmm). Since the discovery of this material, the physical properties of UCd11 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., UCd11–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 UCd11.
