    摘要: A magnetoresistive element generally includes consecutively an antiferromagnetic layer, a first ferromagnetic layer, a non-mangetic layer, and a second ferromagnetic layer. Instead of the non-magnetic layer, the magnetoresistive element may include a combination of a Co layer, a non-magnetic layer, and a Co layer. The antiferromagnetic layer is made of nickel oxide, a mixture of nickel oxide and cobalt oxide, or a laminate of nickel oxide and cobalt oxide. The ferromagnetic layer has a thickness of 1 to 10 nm, and the element has a height of 0.1 to 1 um. The non-magnetic layer has a thickness of 2 to 3 nm, and the antiferromagnetic layer has a thickness of 5 to 30 nm. The magnetoresistive element has an appropriate cross point, outputs an excellent reproduced signal, and has a desirable half-width with respect to the output signal.

    摘要: The invention provides a magnetoresistance effects film including (a) at least two thin magnetic films deposited on a substrate, (b) at least one thin nonmagnetic film interposed between the thin magnetic films, and (c) a thin antiferromagnetic film disposed adjacent to one of the thin magnetic films between which the thin nonmagnetic film is interposed. A bias magnetic field of one of the thin magnetic films induced by the thin antiferromagnetic film has an intensity Hr greater than a coercivity H.sub.C2 of the other of the thin magnetic films which is remote from the thin antiferromagnetic film (Hr>H.sub.C2). The thin antiferromagnetic film has a superlattice structure composed of at least two of NiO, Ni.sub.x Co.sub.1-x O(x=0.1-0.9) and CoO. A ratio of Ni relative to Co in the number of atoms in the superlattice structure is set equal to or greater than 1.0. The magnetoresistance effects film exhibits large linear change in resistance with the hysteresis being small even when a small external field is applied thereto.
