An Nmr Test of Mcmillan's Theory of Incommensurate Charge Density Waves
Abstract
dc:description"We have studied the ('77)Se NMR in single crystal of 2H-TaSe(,2) to test McMillan's proposal regarding charge density waves (CDW). We compare the temperature dependence of the NMR lineshape from 4.2 K to 130 K with predictions based on McMillan's theory, utilizing the recent x-ray diffraction results of Fleming, Moncton, McWhan, and DiSalvo. We employ a theory by Suits to relate the observed lineshape to the alternative theories of the CDW. We confirm McMillan's hypothesis of ""discommensuration""--that the incommensurate CDW is best described by commensurate regions separated by regions of phase slip."
