Abstract
A magnetoresistive detector comprising a stack of layers having different magnetic characteristics (magnetic metal multilayers) wherein there is provision, under the effect of an electrical field, for a transfer of electrons perpendicularly to the layers. To ensure several perpendicular transfers through the same stack of layers, this stack is enclosed between two electrodes, and the electrical conduction of the entire piece is interrupted by a cutting out of the structure in the form of teeth in a Greek key pattern.
