SPIN INJECTOR DEVICE COMPRISING A PROTECTION LAYER AT THE CENTRE THEREOF

摘要

The invention relates to a method for producing a spin injector device (30), comprising the following steps: a) formation of a metal protection layer (22) on a surface (11) of a substrate (10) such as to limit or prevent the oxidation and/or contamination of the surface by its environment, said surface being magnetic and electroconductive, the protection layer being naturally diamagnetic or paramagnetic; and b) formation of an upper layer (32) on the protection layer, which can stimulate a spin polarization, at close to the Fermi level, of the electronic states of the interface between the protection layer and the upper layer using an amplitude and a spin referential defined by the magnetism of the substrate and/or of the surface of the substrate, the upper layer being an organic layer and at least one of the molecular sites of said organic layer having a paramagnetic moment upon contact with the protection layer.
