A Development of a Thin Wire Resistance Thermometer with Isotropic Magneto-Resistance
A thin wire thermometer with isotropic magneto-resistance can be made by adjusting a pitch angle θp in the winding of the sensing wire to a magic angle, arctan(1/√2). Several sensors with different pitch angles were examined and a systematic relationship between their pitch angles and the magneto-resistance was observed. In case of the best sensor, the anisotropy of the magneto-resistance is about 4%, which is reduced from 35% for a commercial platinum resistance sensor.
