| 摘要 |
The invention relates to a GMR sensor assembly comprising a GMR stratification (2), which contains a ferromagnetic layer with a magnetic orientation that can be easily rotated (free layer (3)), a ferromagnetic layer with a fixed magnetic orientation (pinned layer (4)) and a non-magnetic intermediate layer (5) lying therebetween, whereby the pinned layer (4) also forms the first ferromagnetic layer of a synthetic anti-ferromagnet (6), which comprises in addition a second ferromagnetic layer (8) and an intermediate layer (7) lying therebetween. Said sensor assembly is characterised in that the intermediate layer (7) of the synthetic anti-ferromagnet (6) consists of an electrically insulating or high-impedance material.
