摘要：

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 l empty set. Using an on-chip micro-SQUID technology, we have measured a periodic response, with period hip, corresponding to persistent currents in the rings of a typical amplitude of 0.40 coproduct 0.08 nA per ring. Direct comparison with measurements on the same rings but isolated is presented.
