Magnetically sensitive component used as a sensor element operating according to a spin-valve principle in vehicles comprises two magneto-resistive layer systems with a reference layer, an intermediate layer and a detection layer

摘要

Magnetically sensitive component comprises two magneto-resistive layer systems (20) having a GMR or TMR effect produced on a substrate (10), each system having a reference layer (2), an intermediate layer (3) and a detection layer (1). The layer systems are connected as bridge resistors in an electrical circuit in the form of a Wheatstone bridge. At least one of the reference layers has a first partial layer (2a) and a second partial layer (2b), the first layer having a magnetization (m2) and the second layer being an antiferromagnetic partial layer.
