Phys. Rev. Lett. 86, 3124–3127 (2001)Persistent Currents in Mesoscopic Connected RingsReceived 24 July 2000; published in the issue dated 2 April 2001 We report measurements of the low temperature magnetic response of a line of 16 GaAs/GaAlAs connected mesoscopic rings whose total length is much larger than lφ. Using an on-chip micro-SQUID technology, we have measured a periodic response, with period h/e, corresponding to persistent currents in the rings of a typical amplitude of 0.40±0.08nA per ring. Direct comparison with measurements on the same rings but isolated is presented. © 2001 The American Physical Society URL:
