摘要： Articles comprising a quantity of superconductive oxide material can be fabricated by a process that comprises melting of part of an oxide precursor material, with resultant directional resolidification. Exemplary embodiments comprise zone melting and movement of the hot zone through the precursor material. The method can result in superconductive material having improved properties, e.g., higher critical current, as compared to prior art oxide superconductors.

摘要： A method of producing normal-metal-clad superconductive oxide wire, tape and the like is disclosed. The method comprises forming an intermediate body by surrounding a quantity of the oxide powder (e.g., Ba.sub.2 YCu.sub.3 O.sub.6.9) with an appropriate normal metal jacket, reducing the cross section of the intermediate body by any appropriate technique (e.g., drawing or rolling), and heat treating the elongated body such that substantial sintering of the powder results, and such that, after completion of the heat treatment, the sintered oxide has a composition that is associated with superconductivity in unclad bulk samples of the oxide. The latter condition requires that at least the portion of the cladding that is in contact with the oxide powder is substantially inert with respect to oxygen and the oxide under the conditions of the heat treatment. Silver is the currently preferred inert normal metal. Exemplarily, Ag can be used to provide a diffusion barrier with other normal metal (e.g., Ni and Cu) surrounding the diffusion barrier, or the cladding can consist substantially of Ag. Various techniques for preventing oxygen loss and/or restoring lost oxygen from the powder are disclosed. Advantageously the elongated body is appropriately shaped (e.g., wound into a helical coil) prior to the heat treatment. Elongate bodies produced according to the invention can advantageously be used as superconductive magnets, and in a variety of other apparatus and systems.

摘要： Fe--Cr--Co alloys have found application in the manufacture of permanent magnets on account of magnetic properties such as, high coercive force, remanent magnetization, and energy product. A method is disclosed for producing magnetic articles comprising Fe, Cr, and Co from powders comprising elemental or pre-alloyed particles. A powder is mixed with an essentially noncarbonizing organic binder, compressed, heated to remove binder, sintered, and aged. Heating results in essentially complete removal of binder prior to sintering.Magnetic bodies produced according to the disclosed method typically comprise less than 1 weight percent of undesirable nonmagnetic phases and have a maximum energy product of at least 1 million gauss oersted.

摘要： In view of rising cobalt costs, low-cobalt alloys such as, e.g., Fe-Cr-Co alloys are finding increasing use in the manufacture of permanent magnets. Desired magnetic energy product of such magnets is typically at least 1 million gauss-oersted.In the interest of maximizing magnetic energy product per unit weight cobalt, low-cobalt Fe-Cr-Co alloys are processed by solidifying a bulk object from a melt, annealing, quenching, and aging by cooling at rates in a range of 0.1 to 2 degrees C. per hour in a magnetic field. Cold working prior to aging may be used to further enhance magnetic energy product.Resulting magnets have optimized maximum magnetic energy product (BH).sub.max per unit weight cobalt comprised in an alloy.

摘要： Devices such as, e.g., switches, flowmeters, and proximity sensors, as well as implant devices are made comprising an elongated ferromagnetic element. When the element is exposed to a variable magnetic field an electrical signal is obtained between contact points of the element in response to a change in the magnetic field. Preferred elongated elements have a helically deformed microduplex structure as may be produced by heat treatment and plastic twisting of a body of an alloy such as, e.g., an iron-nickel alloy.

摘要： Electrical interconnection is established by means of an anisotropically conductive, composite layer medium comprising electrically conductive particles in a nonconductive matrix material. Enhanced uniformity of conductivity across the medium, and minimized incidence of lateral shorting are achieved as a result of essentially uniform distribution of electrically conductive particles which are also magnetic, such distribution resulting upon application of a magnetic field essentially perpendicular to a layer before or during hardening of the matrix material.

摘要： Disclosed are normal metal-clad superconductive bodies (e.g., wires, ribbons) having a normal metal cladding that is porous during at least a part of the manufacture of the body. The porous cladding permits access of an ambient atmosphere to the superconductive material. Exemplarily, the superconductive material is an oxide such as a (Ba, Y) cuprate, the normal metal cladding comprises Ag particles (or Ag-coated particles), and the body is treated in an oxygen-containing atmosphere. Techniques for producing such a body are also disclosed.

摘要： Wide temperature range magnetic bubble memories are realized by using new compositions of rare earth garnets which require nonlinear bias field for operation over a given temperature range. The bias field structure for providing the corresponding nonlinear bias field includes plates of barium ferrite plus additional plates of Ni-Cu alloys and/or polycrystalline dysprosium (or other rare earths, singly or in combination) iron garnet to provide a nonlinear bias field versus temperature characteristic to match that of the bubble layer.
