G2 = Metal filled nPTMs for use in sensors

This result concerns the use of magnetic nanowires (multilayered or not) in the field of sensors and more particularly in the field of magnetoresistive sensors. The result consists of know-how of the magnetoresistive properties of these materials and their dependence with the various material parameters. The result extends to know-how in device processing of these materials. In the field of magnetic sensors based on giant magnetoresistance, this result brings a way to use the particular measurement geometry with the current flowing perpendicular to the plane of the layers, which allow to increase the amplitude of the magnetoresistive effects by about an order of magnitude.

The magnetic geometry leads to high electrical resistance (of the order of 1k? for a single wire) which is comparable to the resistance of tunnel junctions and two orders of magnitude higher than the typical values for CIP(Current in Plane) GMR systems.
The market sectors which are potentially concerned by this result are the magnetic recording industry, the automotive industry and more generally the magnetic sensor industry including navigation systems, electrical current measurements,
