ABSTRACT:
A ferromagnetic tunnel-junction magnetic sensor includes a first ferromagnetic layer, an insulation barrier layer formed on the first ferromagnetic layer and including therein a tunnel oxide film, and a second ferromagnetic layer formed on the insulation barrier layer, wherein the insulation barrier layer includes a metal layer carrying the tunnel oxide film thereon such that the tunnel oxide film is formed of an oxide of a metal element constituting the metal layer, and wherein the insulation barrier layer has a thickness of about 1.7 nm or less but larger than 1 molecular layer in terms of the oxide forming the tunnel oxide film.
