Abstract :
We investigate the photoresistance of a 140 nm wide electron channel confined by ferromagnetic split gates. We report a series of magneto-oscillations at low magnetic field and investigate their dependence as a function of the microwave frequency. The results exhibit characteristics which suggest plasma excitations along a magnetic edge.
