Abstract :
Paper presents the design of a non-contact angular transducer. We used a GMR-based angular sensor developed in the Center for Superconductivity, Spintronics and Surface Science from Technical University of Cluj-Napoca. The GMR sensor is an application of spin-valves. Magnetoresistance is dependent by angle between magnetic field and magnetic moments in a ferromagnetic material in GMR sensor. We realized a laboratory setup that measure the resistance of sensor. This resistance is strongly dependent by angle between magnetic field applied to the sensor and magnetic moments in material. This dependence is a non-linear one, but the software linearized it.
