Abstract
A magneto-resistance device comprising two layers of ferromagnetic material mutually separated by at least one interposed layer of non-ferromagnetic material, in which at least one of the layers of ferromagnetic material comprises half-metallic material, and preferably both ferromagnetic layers are principally comprised of half-metallic material.
Claims9
A magneto-resistive device comprising two layers of ferromagnetic material mutually separated essentially only by at least one layer of a non-ferromagnetic material, characterized in that said at least one layer of non-ferromagnetic material is electrically insulating and is in contact with one of said layers of ferromagnetic material and at least one of the layers of ferromagnetic material comprises a half-metallic material.
