The inventive magnetic field sensor consists of a sequence of layers comprising at least two ferromagnetic layers which are separated by a non-magnetic layer. One of the ferromagnetic layers is used as a reference layer. The non-magnetic layer is so thin that information about the relative direction of magnetisation of the two ferromagnetic layers can be transmitted in the form of spin-polarised conduction electrons.
