Abstract

We report an Rb87 NMR study of charge-density-wave (CDW) dynamics in single-crystal Rb0.30MoO3 under applied bias. The monoclinic compound Rb0.30MoO3 undergoes a CDW-driven phase transition at 181 K below which a number of effects associated with conductivity via a moving CDW have been observed. Application of current densities up to 2 A/cm2 appear to show the development of induced relaxation at applied fields above a 0.5 V/cm threshold, a field that is nearly an order of magnitude above the observed threshold for electrical nonlinearity.
