Anomalous behavior of the quasi-one-dimensional quantum material Na${}_2$OsO${}_4$ at high pressure

Raimundas Sereika, Kazunari Yamaura, Yating Jia +10

Na${}_2$OsO${}_4$ is an unusual quantum material that, in contrast to the common 5$d^2$ oxides with spins = 1, owns a magnetically silent ground state with spin = 0 and a band…
