ABSTRACT

We calculate the average persistent current in a normal conducting, mesoscopic ring in the diffusive regime. In the presence of magnetic impurities, a contribution to the persistent current is identified, which is related to fluctuations in the electron spin density. Assuming a spin-flip scattering rate which is comparable to the Thouless energy Ec and low temperature, this new contribution to the persistent current is of the order I ∼ Ec2(kTφ0), which is considerably larger than the persistent current induced by the electron-electron interaction.
