Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


The planar Hall effect (PHE) is intimately related to the anisotropic magnetoresistance (AMR). However, while AMR-based magnetic sensors have been commercially available for decades and are widely used in a variety of applications, PHE-based sensors have been mostly the subject of research. The reason for that is most probably the superior performance that has been exhibited by the AMR sensors. In this chapter, we review the work that has been done in the field of PHE sensors with emphasis on the PHE sensors developed by the authors. The performance of these sensors exceeds the performance of commercially available AMR-based sensors and has the potential of competing even with bulkier ultra-sensitive sensors such as flux-gate and atomic magnetometers. We review the physical origin of the effect, the use of shape to tailor the magnetic anisotropy on demand and the optimization process of the fabrication details of the sensor and its amplification circuit.
