1 Ailion, David CharlesThermal fluctuations and NMR spectra of incommensurate insulatorsThe 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 insulators1994
2 Ailion, David CharlesThermal fluctuations and NMR spectra of incommensurate systemsIn the presence of thermal fluctuations the incommensurate NMR line shape is a convolution of a static inhomogeneous with a dynamic homogeneous line shape which can be determined separately by 2D NMR. The form of the dynamic line shape and its variation over the inhomogeneous NMR spectrum permit a ...Thermal fluctuations; NMR; Incommensurate systems; Line shape1992
