Narrow-band "noise" in NbSe 3 as a function of magnetic field and temperature: A reassessment
Abstract
We report the results of a Narrow-band "noise" (NBN) study in NbSe 3 for magnetic fields up to 19 T and temperatures as low as 15 K. A pulsed set up was used to achieve measurements up to 400 MHz. We show that the relation between the Charge Density Wave CDW current J CDW and the NBN frequency ν o is not linear at low temperature and low frequency (<30 MHz). We find a decrease of dJ CDW/dν o with decreasing temperatures for both transitions. This new effect is interpreted in terms of the interaction of quasiparticles with the CDW current. Changes in dJ CDW/dν o due to the magnetic field are also analyzed.
