Abstract
The theory of Josephson-type oscillations in a moving charge-density wave proposed by Barnes and Zawadowski is extended to include the interaction with spin- magnetic impurities in the presence of a constant magnetic field. The current oscillations of the Josephson type are found to exhibit a magnetic field dependence providing that the conduction electron and impurity factors are different. This effect could be used experimentally to distinguish between classical and Josephson-type contributions to the narrow-band noise in materials such as Nb and Ta doped with magnetic impurities.
