Nuclear Spectroscopy on Charge Density Wave Systems

Nuclear magenetic resonance (NMR), nuclear quadrupole resonance (NQR), time differential perturbed angular correlations (TDPAC) and the Mossbauer effect (ME) have been applied to the study of charge density wave (CDW) systems. These hyperfine techniques provide unique tools to probe the structure and symmetry of commensurate CDWs, give a clear fingerprint of incommensurate CDWs and are ideally suited for CDW dynamics. This book represents an attempt in the series "Physics and Chemistry of Materials with Low-dimensional Structures" to bring together a group of scientific results obtained by nuclear spectroscopy related to charge density wave (CDW) phenomena in pseudo one- and two-dimensional systems. The individual chapters contain: the theory of CDWs in chain-like transition metal tetrachalcogenides is one topic discussed; NMR, NQR, TDPAC and ME investigations of layered transition metal dichalcogenides; NMR studies of CDW-transport in chain-like NbSe 3 and molybdenum bronzes; mulitnuclear NMR of KCP, high resulution NMR of organic conductors. THis book should be of interest to graduate students and scientists who want to acquire a broader knowledge of nuclear spectroscopy techniques applied to CDW systems.
