摘要：

Persistent currents: The magnetism of Au nanoparticles might result from persistent currents. Limited portions of a given sample may even support self-sustained currents, thus exhibiting remnant magnetization and hysteresis. Observing such a quantum effect at room temperature with user-friendly samples opens unforeseen possibilities. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
