| 摘要 |
A magnetoresistive sensor system comprises a soft magnetic measuring layer system (4) and a hard magnetic reference layer system (2). The reference layer system has an artificial antiferromagnetic layer composite (6) with a reference layer (8) and an antiferromagnetic layer (10) having a thickness measured so that it has an uniaxial anisotropy. Preferred Features: The antiferromagnetic layer is arranged on the side of the artificial antiferromagnetic layer facing away from the measuring layer system. The antiferromagnetic layer is made from NiO, FeMn, IrMn, NiMn, PtMn, CrPtMn, RhMn or PdMn.
