Current-flux characteristics in mesoscopic nonsuperconducting rings
arXiv:1008.2781 · doi:10.1088/0953-8984/22/42/422201
Abstract
We propose four different mechanisms responsible for paramagnetic or diamagnetic persistent currents in normal metal rings and determine the circumstances for change of the current from paramagnetic to diamagnetic ones and {\it vice versa}. It might qualitatively reproduce the experimental results of Bluhm et al. (Phys. Rev. Lett. 102, 136802 (2009)).
