THIN FILM DEVICE WITH PERPENDICULAR EXCHANGE BIAS

摘要

A perpendicular exchange biased device (10) comprises a layer of buffer material (14) on a surface of a substrate (12), a layer offerromagnetic material (18) on a surface of the buffer layer, wherein the magnetization of the ferromagnetic layer lies in a direction perpendicular to the plane of the layer of ferromagnetic material, and a layer of antiferromagnetic material (22) on a surface of the layer of ferromagnetic material. A method of making a perpendicular exchange biased device comprising positioning a layer of buffer material on a surface of a substrate, positioning a layer of ferromagnetic material on a surface of the layer of buffer material, wherein the magnetization of the ferromagnetic layer lies in a direction perpendicular to the plane of the layer of ferromagnetic material, and positioning a layer of antiferromagnetic material on a surface of the layer of ferromagnetic material is also included.
