Abstract
We report measurements of the low temperature magnetic response of a line of 16 GaAs/GaAlAs \emph{connected} mesoscopic rings whose total length is much larger than . Using an on-chip micro-\textsc{squid} technology, we have measured a periodic response, with period , corresponding to persistent currents in the rings of typical amplitude per ring. Direct comparison with measurements on the same rings but \emph{isolated} is presented.
