Phys. Rev. Lett. 67, 3578–3581 (1991)Magnetic response of a single, isolated gold loopReceived 12 August 1991; published in the issue dated 16 December 1991 Measurements have been made of the low-temperature magnetic response of single, isolated, micron-size Au loops. The magnetic response is found to contain a component which oscillates with the applied magnetic flux with a fundamental period of Φ0=h/e. The amplitude of the oscillatory component corresponds to a persistent current of ≃(0.3–2.0)evF/L, 1 to 2 orders of magnitude larger than predicted by current theories. © 1991 The American Physical Society URL:
