The layer system having an increased magnetoresistive effect contains at least one soft magnetic detection layer, a non-magnetic decoupling layer, which rests on the detection layer, and a layer partial system, which is located at a distance due to the decoupling layer, forms an artificial antiferromagnet, and which is decoupled from the detection layer. This partial system (5) comprises a first ferromagnetic and a second ferromagnetic layer (11 and 12). The first ferromagnetic layer (11) should be antiferromagnetically coupled (K2) to the second ferromagnetic layer (12) via a non-magnetic coupling layer (13). In addition, the side of the first ferromagnetic layer (11) facing away from the coupling layer (13) should be provided with an antiferromagnetic additional layer (14) and be exchange-coupled (K3) thereto and, in addition, should have a material composition that differs from the second ferromagnetic layer (12). |
