THREE TERMINAL MAGNETORESISTIVE MAGNETIC FIELD DETECTOR IN WHICH VOLTAGES OF OPPOSITE POLARITY RELATIVE TO GROUND ARE APPLIED TO OPPOSITE ENDS

摘要

Disclosed herein is a detector of local magnetic field, in which metallic electrodes are connected to the both ends and central part of at least one semiconductor having a magneto resistive characteristic thereby to form at least one magneto resistive element having three terminals, said element being arranged on a plane, whereby presence of a local magnetic field in said element can be detected from a voltage appearing across each of the central electrodes of said elements and a predetermined reference point.
