Abstract :
Magnetic field measurement constitutes a good method to know some magnitudes related to it. In this work, we present a novel spin-valve bridge magnetoresistance sensor and the design of an instrumentation system with the aim to characterize several properties of it. Experimental results derived from the characterization process are shown, and a novel measurement and control application of these sensors is presented.
