摘要： The invention is embodied in an anisotropic, soft magnetic thin film article comprising a cobalt-iron-chromium-nitrogen (Co--Fe--Cr--N) alloy. The thin film is formed such that the alloy has a relatively high saturation magnetization (4.pi.M.sub.s), e.g., greater than approximately 8 kilogauss (kG), a relatively low coercivity (H.sub.c), e.g., less than approximately 2.0 oersteds (Oe), a relatively high squareness ratio (M.sub.r /M.sub.s), e.g., greater than approximately 0.90, and a relatively high anisotropy field (H.sub.k), e.g., greater than approximately 20 Oe, in an as-deposited condition or, alternatively, with a relatively low temperature treatment, e.g., below approximately 300.degree. Celsius. The inventive films are suitable for use in electromagnetic devices, e.g., in microtransformer cores, inductor cores and in magnetic read-write heads.

摘要： Embodiments of the invention include a transformer device having a saturation region for limiting ingress noise and other noise. The transformer comprises a magnetic core, an input coil and an output coil arranged so that the output signal caused by the magnetic linkage between the input and output coils through the magnetic core is based on the magnitude of the input signal. According to an embodiment of the invention, the magnetic core includes a saturation region that limits the output signal regardless of the magnitude of the input signal once the saturation region reaches its saturation magnetization state. The saturation region comprises a reduced saturation magnetization level caused by a geometrically constricted region of the magnetic core or, alternatively, by a modified, magnetic-equivalent region having properties similar to a geometrically constricted region.

摘要： In accordance with the invention, a tunable fiber grating comprises a fiber grating secured between a pair of magnets so that magnetic force (repulsive or attractive) applied to the magnets is transmitted to the grating. An electromagnet is disposed adjacent the magnets for applying the field to magnetize them. Control of the current applied to the electromagnet permits control of the force transmitted to the fiber grating and, thus, control of the grating strain, spacing and reflection frequency. In a preferred embodiment the electromagnet is actuated to produce magnetic pulses which control the remanent force between the two magnets, eliminating the need for continuous power. An add/drop multiplexer employing the tunable gratings is described.

摘要： A novel non-mechanical optical fiber switch contains a magneto-optic element and a tubular magnet. The magneto-optic element is disposed within the field of the magnet but outside of the magnet bore. The beam of radiation from the switch input to the switch output passes through the axial bore of the magnet. The magnet contains magnetically anisotropic material, preferably a deformation-aged alloy having Fe, Cr and Co as major constituents. The switch is advantageously used in optical fiber communication systems.

摘要： A technique that involves selective removal of material from a surface of a polycrystalline diamond (polyD) film such that a non-planar surface results. Exemplarily the technique is used to form polyD optical elements, e.g., convex or concave lenses, or Fresnel lenses, including arrays of such lenses. The technique involves maintaining on appropriately shaped hot template body in intimate contact with a polyD surface for a time (e.g., in the range 1-1000 hours) sufficient to result in formation of the desired feature in the polyD surface. The template body involves a rare earth metal (La and Ce are preferred), Mn and/or Fe, and the temperature is below the melting temperature of the template body. Removal of "spent" template material by, e.g., chemical etching and finishing of the polyD feature, e.g., by laser ablation and/or polishing, are contemplated.

摘要： A method of making a ribbon-like or sheet-like superconducting composite body is disclosed. The method is well suited for making long lengths (e.g.,>100m) of ribboon or large areas (e.g.,>100cm.sup.2) of sheet-like composite. The method comprises forming a Bi-Sr-Ca-Cu-oxide-containing layer on a metal (exemplarily Ag) substrate, and mechanically deforming (typically by rolling) the thus formed composite such that the oxide is densified to more than 80% of the theoretical density. Subsequently the oxide layer is at least partially melted and allowed to re-solidify such that a large portion of the oxide crystals has c-axis alignment. After appropriate heat treatment in an O.sub.2 -containing atmosphere, thus produced superconductor ribbons or sheets can have high J.sub.c).gtoreq.10.sup.4, frequently >10.sup.5 A/cm.sup.2) for temperatures less than about 20K and in magnetic fields less than about 5T.
