High-field ultrasound study of elastic constants and possible magnetic symmetry transformations in UO2

E. A. Tereshina-Chitrova, L. V. Pourovskii, S. Khmelevskyi +2

In this study, we probe the coupling between magnetism and lattice dynamics in UO2, a 3k antiferromagnet that undergoes magnetic ordering below its Neel temperature (TN) of 30.8 K.…
