A Wheatstone bridge GMR sensor can be used for analog magnetic field measurements. This paper deals with hysteresis effects in GMR sensor, which is the major source of measurement error. Experiments are conducted by measuring hysteresis curves between applied magnetic field and sensor output voltage...
