We present measurements done on a novel device consisting of two concentric quantum rings realized by local anodic oxidation in a GaAs/AlGaAs heterostructure. The outer ring is connected to external leads while the inner ring is only Coulomb-coupled to the rest of the system. We studied the electronic transport through the outer ring in dependence of an external magnetic field and found a ...
