Abstract

The low-temperature longitudinal and Hall resistances of a two-dimensional electron gas are studied in the presence of a magnetic barrier created under the edge of a thin ferromagnetic film. An in-plane external magnetic field allows us to tune the barrier height within the classically transmissive regime. A theoretical model is presented that predicts the size and shape of the resistance ...
