Simulación numérica de un nuevo sensor de anisotropía magnética//Numeric Simulation of a new magnetic anisotropy sensor

The aim of this study is to evaluate the applicability of the residual stresses determination methodology, previously used with magnetic anisotropy sensor SAM0, with the new more advanced sensor SAM2. The characterization of the new sensor response function was carried out using the numeric simulation. A periodic behavior with respect to the rotated angular positions for a given value of magnetic anisotropy was observed. A lineal dependence between the EMF values measured with the new sensor and the sample magnetic anisotropy was demonstrated. The EMF measured in the three SAM2 circuits are equivalent to those obtained for three SAM0 sensors, oriented 120° between them. The applicability of the SAM0 response function to describe the measurements made with the new sensor was established.
