We study the Hall effect at low magnetic fields in ballistic GaAs-AlxGa1 - xAs heterostructure Hall junctions that contain four, three, two, or one narrow constrictions in the junction region. These geometries are investigated to determine the necessary condition for observation of the quenching of the Hall effect. We find that only the four constriction geometry shows a genuine quenching. By applying a backgate bias, quenching is produced within a finite electron density range. Our results are interpreted within the framework of the Büttiker-Landauer formulas in terms of junction scattering of the electrons. © 1990.
