NMR study on single crystal Ba<sub>2</sub>LiOsO<sub>6</sub>

ORAL

Abstract

Nuclear magnetic resonance (NMR) measurements on single crystals of Ba2LiOsO6 were carried out to test the universality of theoretical models based on anisotropic exchange interactions [1]. The results are compared with NMR findings on its isostructural and isovalent compound Ba2NaOsO6. Ba2LiOsO6 displays significant line broadening at low temperature, but no well-defined line splitting like its Na counterpart [2]. In addition, the spin-lattice relaxation and linewidth of its spectrum undergoes an abrupt change at 6 T. The implications of these findings will be discussed.
