Abstract:

NMR and NQR investigations on the complex magnetic structure in the ordered state as well as phase transitions in two isostructural quasi-1D edge-shared cuprates LiCu2O2 and NaCu2O2 have been performed. While LiCu2O2 exhibits a magnetic phase transition at T-c = 24 K, NaCu2O2 orders magnetically at around 13 K. Li-6,Li-7 and Na-23 NMR spectra in LiCu2O2 and NaCu2O2, respectively, provide an unambiguous experimental evidence that below T-c an incommensurate in-chain helical spin structure is established in both compounds. However, the features of the observed low-temperature NMR and NQR spectra are different pointing to different properties of the helical magnetic structure. (C) 2007 Elsevier B.V.
