Patterned two-dimensional electron gas (2DEG) systems into micrometer Hall bars can be used as Hall magnetosensors to provide detailed information on the magnetic field distribution. In this way, ballistic Hall probes have already been studied and used successfully. Here, the response function of a Hall sensor is determined in the diffusive regime, which allows this device to be used as a magnetosensor for the determination of inhomogeneous magnetic field distribtutions. Furthermore, the influence of the geometry of the Hall bar on this response function, such as circular corners and asymmetry in the probes, is also investigated and appears to be non-negligible.
