Charge-Density-Wave Carrier Concentration in NbSe3as a Function of Magnetic Field and Temperature

Abstract
We report measurements of the resistance and narrow-band noise in NbSe3 for magnetic fields from 0 to 10 T and temperatures from 30 to 55 K. We find that a magnetic field effects a change of less than 5% on the charge-density-wave carrier concentration obtained from the slope of the current versus frequency curves. This disagrees with some previously reported measurements and resolves an existing controversy. Our work also implies that the increase in the resistance anomaly with magnetic field is not related to an increase in the carrier concentration.
