![]() | Ailion, David Charles | Thermal fluctuations and NMR spectra of incommensurate insulators | The effects of thermal order-parameter fluctuations on the NMR line shape of incommensurate systems are evaluated within the mean-field Landau theory and the results are compared with the 8 7Rb and 3 9K 1/2 -1/2 NMR spectra of Rb2ZnCl4 and K2Se04 just below the paraelectric-incommensurate transition... | NMR spectra; Thermal fluctuations; Line shapes; Incommensurate insulators | 1994 |
