Effect of magnetic field on the dynamics of impurities in metallic systems
Al'tshuler B. L., Spivak B. Z.
A magnetic field can substantially alter the probability for the hop of an impurity or for a transition in a two-level system in a disordered metal. The effect stems from a change in the energy of the interaction of an impurity atom with conduction electrons when a magnetic field is imposed. A similar dependence of the hopping probability on the superfluid current is predicted in disordered superconductors.
