Abstract

This paper deals with the numerical modeling of the electric potential distribution inside semiconductor Hall effect devices, under the presence of non-uniform magnetic fields. The model is applied to study miniaturized sensors for the detection of superparamagnetic nanobeads. The magnetic moment resolution is evaluated for different Hall probe geometries, by varying the bead size and its distance from the sensor surface.
