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.

The invention relates to a magnetoresistance material, i.e. a conductive material that exhibits magnetoresistance, which is an inhomogeneous system consisting of a nonmagnetic matrix and ultrafine particles of a ferromagnetic material such as Co or Ni--Fe--Co dispersed in the nonmagnetic matrix. With the aim of reducing deterioration of the magnetoresistance effect, an alloy or mixture of at least two metal elements selected from Cu, Ag, Au and Pt is used as the material of the nonmagnetic matrix. Optionally, the nonmagnetic matrix may contain a limited quantity of a supplementary element selected from Al, Cr, In, Mn, Mo, Nb, Pd, Ta, Ti, W, V, Zr and Ir. A film of the magnetoresistance material can be formed on a substrate, and it is optional to interpose a buffer layer between the film and the substrate and/or cover the film with a protective layer.

An object of the present invention is to provide a low-priced and highly reliable high-vacuum hermetic seal package. To this end, a method of manufacturing a hermetic seal package according to the present invention is a method of manufacturing a hermetic seal package by anodically bonding an opening of a cylindrical body for forming an outer frame and the outer edge of a flat glass plate to each other, characterized in that anodically bonded surfaces are 0.04 mm to 200 mm in width and not more than 0.20 μm in surface roughness, the cylindrical body consists of a metal consisting of at least one of Fe, Ni and Co or an alloy or conductive ceramics mainly composed of this metal, the glass plate contains alkaline metal ions, and the quantity of inert gas permeation on bonded portions is 1.0×10−15 Pa.m3/s to 1.0×10−8 Pa.m3/s after anodic bonding.

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.

A magnetoresistance effect film is disclosed. This magnetoresistance effect film comprises a substrate, at least two ferromagnetic thin films stacked one over the other on the substrate with a non-magnetic thin film interposed therebetween, and an antiferromagnetic thin film arranged adjacent to one of the ferromagnetic thin films. The antiferromagnetic thin film is a superlattice formed of at least two oxide antiferromagnetic materials selected from NiO, Ni.sub.x Co.sub.1-x O (0.1.ltoreq.x.ltoreq.0.9) and C.sub.o O. A biasing magnetic field Hr applied to the one ferromagnetic thin film located adjacent the antiferromagnetic thin film is greater than coercive magnetic force Hc.sub.2 of the other ferromagnetic thin film.
