Abstract :
We studied the temperature stability of resistivity and Hall resistivity of percolating granular NiFe-SiO2 films upon annealing. Both the resistivity and the Hall resistivity were found to be stable below 300°C, and at 230°C for as long as 52 hours. The feasibility of linear field sensors based on the giant Hall effect at high temperatures is discussed
