Observation of Persistent Currents in Mesoscopic Connected Rings

Mesoscale and Nanoscale Physics 2009-10-31 v3

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 lϕl_{\phi}. Using an on-chip micro-\textsc{squid} technology, we have measured a periodic response, with period h/eh/e, corresponding to persistent currents in the rings of typical amplitude 0.40±0.08nA0.40\pm 0.08 nA per ring. Direct comparison with measurements on the same rings but \emph{isolated} is presented.
