Abstract
We report on the photoresistance of a magnetic quantum wire obtained by applying a gradient of magnetic field to a two-dimensional electron gas. Electron transmission through the magnetic wire increases by an order of magnitude under microwave irradiation and exhibits frequency-dependent magneto-oscillations as a function of the in-plane magnetic field. Both results are fully consistent with microwave-coupled Luttinger liquid edge channels which interfere at two pinning sites in the fashion of a Mach-Zehnder interferometer.
