Abstract
A magnetoresistive device includes a laminated film, and a mechanism for applying sense current in a direction of lamination in the laminated film, wherein the laminated film includes a first ferromagnetic layer having a substantially fixed direction of magnetization, a second ferromagnetic layer having a freely variable direction of magnetization according to an external magnetic field, the second ferromagnetic layer including a non-magnetic metal layer, and two or more ferromagnetic metal layers separated from each other by the non-magnetic metal layer in the direction of lamination, and a non-magnetic intermediate layer that separates the first and second ferromagnetic layer from each other.
