Offset Stability of GMI Magnetic Field Sensors

Original language description

We show that the performance of GMI field sensors is influenced by perming effect and offset temperature drift. Magnetic field shocks in permalloy material cause offset shifts as high as 3 uT. Perming error can be reduced by increasing the measurement current. Large temperature offset drift of 283 nT/K and -409 nT/K was observed for permalloy and amorphous sensor respectively. Temperature sensitivity can be partly suppressed by double-core design.
