Magnetoresistance device including layered ferromagnetic structure, and method of manufacturing the same

摘要

A layered ferromagnetic structure is composed of a first ferromagnetic layer (11) positioned over a substrate (1); a second ferromagnetic layer (13) positioned over the first ferromagnetic layer (11); and a first non-magnetic layer (12) placed between the first and second ferromagnetic layers (11, 13). The top surface of the first ferromagnetic layer (11) is in contact with the first non-magnetic layer (12). The first ferromagnetic layer (11) includes a first orientation control buffer (22) that exhibits an effect of enhancing crystalline orientation of a film formed thereon.
