Magneto-resistive sensor element for measurement of external magnetic field angle, especially in bridge circuits, has outer sensor layer comprised partially or completely of individual segments

摘要

Element comprises a first magnetic layer (1) whose magnetic field direction acts as a reference, a second non-magnetic layer (2) and a third magnetic layer (3) whose magnetization direction is influenced by external magnetic field. Third layer (3) is partially or completely formed from individual segments (3a).
