Confirmation of Mcmillan's Concept of Discommensurations in 2h-Tantalum-Diselenide
Abstract
dc:descriptionWe have studied the ('77)Se nuclear magnetic resonance spectra in a single crystal sample of 2H-TaSe(,2) to study the charge density wave (CDW) in this compound and to test a concept put forth by McMillan. We compare the temperature dependence of the NMR lineshape obtained by Couturie from 4.2 K to 130 K with a lineshape theory which encompasses McMillan's theory as well as the theory which preceded McMillan's. We have utilized precision electrical resistance measurements which, when compared to the recent x-ray diffraction results of Fleming, Moncton, McWhan and DiSalvo, provide us with an independent measure of the CDW properties. Our results confirm McMillan's hypothesis.
