Claim:
1. A method of forming a sensor comprising: forming a first electrode; forming a second electrode; forming a detector region; electrically coupling the detector region to the first electrode and the second electrode; forming the detector region to include a first layer comprising a topological insulator; the topological insulator having a conducing path along a surface of the topological insulator; forming the detector region to further include a second layer comprising a first insulating magnetic coupler; wherein a magnetic field applied to the detector region changes a resistance of the conducting path; wherein the first insulating magnetic coupler amplifies the magnetic field applied to the detector region; and forming the detector region to further comprise a third layer comprising a second insulating magnetic coupler; wherein the second insulating magnetic coupler amplifies the magnetic field applied to the detector region.
