NMR study on single crystal Ba2LiOsO6

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.
