Abstract
A sensor device for detecting the direction of an external magnetic field using a magnetoresistive sensor element, includes a GMR multilayer system having at least one soft magnetic measurement layer, at least one harder bias layer and at least one nonmagnetic intermediate layer disposed therebetween. The sensor element is to include at least two element parts, the multilayer systems of which are constructed on a common substrate and the magnetization directions of which include an angle which is unequal to 0° or unequal to 180° and the measurement signals of which are to be evaluated in common.
