Abstract:
An arrangement for measuring a magnetic field withat least one first layer assembly (8) and at least one second layer assembly (10), whereby the first layer assembly (8) and the second layer assembly (10) have a hard magnetic layer (16), a layer (18) effective as a tunnel barrier and adjacent the hard magnetic layer, and a layer (18) effective as a tunnel barrier layer adjacent the soft magnetic layer (20) and whereby the layer assemblies (8, 10) are arranged in a bridge circuit (24) for determining the electrical resistance, characterized in that the second layer assembly (10) additionally has an electrically conductive antiferromagnetic layer (22), adjacent the soft magnetic layer (20) or an electrically-conductive synthetic antiferromagnet is adjacent the soft magnetic layer (20).
