Insight into the crystal structures and physical properties of the uranium borides UB$_{1.78±0.02,}$ UB$_{3.61±0.041}$ and UB$_{11.19±0.13}$

Résumé

In this study we reported the synthesis of three polycrystalline uranium borides UB$_{1.78±0.02,}$ UB$_{3.61±0.041}$ and UB$_{11.19±0.13}$ and their analyses using chemical analysis, X-ray diffraction, SQUID magnetometry, solid-state NMR, and Fourier transformed infrared spectroscopy. We discuss the effects of stoichiometry deviations on the lattice parameters and magnetic properties. We also provide their static and MAS-NMR spectra showing the effects of the 5f-electrons on the $^{11}$B shifts. Finally, the FTIR measurements showed the presence of a local disorder.
