Abstract
The symmetry properties under magnetic-field reversal are reported for the elements of the admittance matrix of a set of probes that couple capacitively to a nondegenerate two-dimensional electron system, which in itself is not connected to an electron reservoir. Strong asymmetries are observed in multiterminal measurement configurations (three probes or more), whereas two-terminal measurements are symmetric. The asymmetries are explained in terms of classical edge magnetoplasmons and satisfy the generalized Onsager-Casimir symmetry requirements.
