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.
