Magnetic Properties of Gold Nanoparticles: A Room-Temperature Quantum Effect

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 samp...

Zusammenfassung:	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.
