摘要： Laminated films of SiAlFe alloy (sendust) providing optimized magnetic and mechanical properties for magnetic shield and magnetic pole tip applications are described. A multilayered magnetic structure including a seed layer of a first sendust alloy and a bulk layer of a second sendust alloy overlying the seed layer provides provides greatly improved anisotropic field and soft magnetic characteristics for the structure over a relatively wide range of compositions for the sendust material used for the bulk layer. The seed layer can be a single sendust layer or, alternatively, can be a multilayered structure including layers of a gas-doped sendust material and layers of non-doped sendust material formed in an alternating sequence. The dopant gas is a gas such as nitrogen, oxygen or air, for example. Because of the hardness exhibited by sendust films, the described multilayered sendust films are excellent candidates for magnetic shields and inductive pole tips exposed at the air bearing surface of a transducer.

摘要： A thin film magnetic structure for use as a flux guide in a magnetic recording system has tapered edges transverse to the magnetization axis of the film. The tapered edges eliminate magnetic edge domains and thereby assure a single magnetic domain in the film structure. Thus, Barkhausen noise is essentially eliminated from the signal read by the film structure from the magnetic recording medium.

摘要： A single layer film is deposited onto a substrate at room temperature from two sources, one source being a magnetic material, the other being a non-magnetic or weakly-magnetic material. The film is annealed for predetermined time in order to induce phase separation between the magnetic clusters and the non-magnetic matrix, and to form stable clusters of a size such that each magnetic particle, or cluster, comprises a single domain and has no dimensions greater than the mean free path within the particle.

摘要： A wet gravure coating of fine magnetizable particles can be smoothed by a rectangular piece of flexible film that is secured at one end in flat jaws of a clamp to leave its opposite end free to drag against the coating, thus causing the flexible film to form an arc between its secured end and the convergence of the flexible film with the wet coating. The jaws also secure a flat plate which has a straight edge that deflects the arcuate portion of the flexible film toward the coating along a line extending transversely across the full width of the flexible film. The plate can be repositioned during the smoothing to adjust the radius of curvature of the arc in order to correct any defects that may appear in the smoothed coating. When the backing web is wide and is advanced at economically high speeds, the free end of the flexible film can be tensioned so that its trailing edge becomes bowed and in contact with the coating over its full width.

摘要： A MR element which has a basically three-layered structure wherein the first and the second magnetic layer sandwich the nonmagnetic layer or of a basically five-layered structure wherein nonmagnetic layers are sandwiched between the first and second magnetic layers and between the second and third magnetic layers, respectively. The MR element of such arrangement offers a surprisingly large MR ratio under application of a sufficiently low magnetic field despite such a simple arrangement thereof.

摘要： The present invention provides increased stabilization of the magnetization of a single domain thin magnetic film over that attainable in the rectangular thin film known in the prior art by shaping the magnetic film as a rhomboid rather than as a rectangle. Practice of the invention teaches angling the transverse sides of the film with respect to the longitudinal sides either at an angle equal to, or smaller than, the angle at the bias point of the magnetization with respect to the direction of the easy axis, as established by an external bias field. Under these conditions the biased magnetization of the film, being either parallel to, or at a positive angle with respect to the transverse sides of the rhomboid, either generates no charges at the transverse edges of the film, or actually generates charges which produce a field parallel to the longitudinal component of the magnetization which stabilizes the magnetization of the single domain rather than destabilizes it.
