In this work we present a new method to fabricate planar Hall sensors from GaAs AlGaAs heterojunctions, which can be used to examine the local stray field at a specific section of a micron-sized magnet. Instead of mesa etching we implanted oxygen ions with an energy of 1.5 keV which deplete the two- dimensional electron gas underneath the exposed areas but leave the wafer flat. Planar ...
