摘要： A method of producing a thin-film magnetic head on a carrier (1) comprising depositing an electrically conducting plating-base (2) and electroplating flux conductors (4a, 4b) and a magnetically insulating layer (8) on the plating-base. This provides a planar structure on which an electrically insulating layer (9) and a magneto-resistance element (10) are applied. The plating-base (2) also constitutes the gap layer.

摘要： A magnetic structure in which magnetic domains can propagate. The structure comprises a monocrystalline gallium garnet substrate having a surface which is substantially parallel to a (100) crystal plane and on which a layer of rare-earth iron garnet, having a partial substitution of maganese ions in iron sites, is grown in compression. By using a substrate material having a lattice constant between 12.23 and 12.38 .ANG., the compression of a epilayer having certain desired magnetic properties can be adjusted by adjusting the incorporation of lutetium and yttrium ions in the epilayer, without adversely affecting magnetic properties of the layer.

摘要： A device for propagating magnetic domains includes a monocrystalline nonmagnetic substrate of a rare earth gallium garnet bearing a layer of an iron garnet capable of supporting local enclosed magnetic domains. The iron garnet layer is grown in compression on a (100) face of the nonmagnetic substrate. The iron garnet comprises manganese in part of the iron sites of its crystal lattice, and comprises yttrium and at least one representative selected from the group comprising bismuth and the rare earth metals in the dodecahedral lattice sites. Such a magnetic garnet has a very high uniaxial anisotropy and a high domain mobility. These properties make the device extremely suitable for propagating submicron magnetic domains having diameters as small as 0.4 .mu.m.

摘要： A device for propagating magnetic domains, comprising a monocrystalline nonmagnetic substrate of a material having a garnet structure, and a layer of an iron garnet grown epitaxially on the nonmagnetic substrate. In the dodecahedral lattice sites, the iron garnet comprises at least a bismuth ion and a rare-earth ion selected from the group consisting of lutetium, thulium, and ytterbium. Such a magnetic garnet combines very high uniaxial anisotropy with a high domain mobility, which properties make the device extremely suitable for the propagation of magnetic domains having diameters from approximately 1 to approximately 2 .mu.m under the influence of comparatively low driving fields.
