Abstract

Varying the magnetic field in the integer quantum Hall regime induces
large eddy currents inside the two-dimensional electron system. Using
multiple single-electron transistor electrometers as highly sensitive
and very small potential probes on top of quantum Hall samples, we can
show that these eddy currents are induced in the incompressible region
close to the Hall bar mesa edge. (C) 2003 Published by Elsevier B.V.
