Abstract

According to this method for producing a magnetic tunnel junction, a film of a dielectric material capable of acting as a tunnel barrier is deposited between two nanocrystalline or amorphous magnetic films. The dielectric material constituting the tunnel barrier consists of an at least partially crystalline perovskite, and said material is deposited by ion beam sputtering in a vacuum chamber.
