Process for making a magnetoresistive magnetic sensor and sensor obtained using this process

摘要

Process for manufacturing a magnetoresistive magnetic sensor using in magnetometry and a sensor obtained using this process. According to the invention, the sensor comprises two concentrator guides (32, 34) embedded in a substrate (20). The inclined flanks of these guides correspond to the crystallographic planes of the substrate (20). The magnetoresistance (40) is placed on the substrate (20) between guides (32, 34).
