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.
Claims15
A magnetoresistive transducer comprising at least one layer of a composite material comprising at least two different particles having different magnetic characteristics, wherein said transducer also comprises;
- two layers of conductive material enclosing the layer of composite material;
- at least two electrodes located on at least one of the layers of conductive materials in zones that are distant from each other along the plan of the layers;
- the layer of composite material and said at least one layer of conductive material that bears an electrode comprising at least one interruption of electrical conduction located between the zones comprising the electrodes.
