摘要： A superconducting switch is composed of anisotropic magnetic material. The switch has a first superconducting section, a variable resistive section and a second superconducting section. An external magnetic field is applied so that the first and second superconducting sections remain superconducting and the resistive section changes resistance when the magnetic field applied exceeds the critical field of the variable resistance section. The different critical field regions are achieved by exploiting the natural critical field anisotropy of the ceramic superconductors (a previously unobserved phenomena in metal superconductors). By making the different sections with different orientations they will exhibit different critical field valves for a given direction of applied fields. The state of the switch is changed by either increasing or decreasing the external magnetic field about the critical field value of the resistive section of the switch. The first superconducting section is connected to the resistive section and the resistive section is connected to the second superconducting section to form a switch circuit. The change in the current flowing through the switch indicates the state of the switch.

摘要： A HTS switch includes a HTS conductor for providing a superconducting path for an electrical signal and an serpentine wire actuator for controllably heating a portion of the conductor sufficiently to cause that portion to have normal, and not superconducting, resistivity. Mass of the portion is reduced to decrease switching time.

摘要： A superconducting non-linear device comprising a superconducting conductor, a current source associated with the conductor for applying to the conductor a bias current, and a control device associated with the current source for selectably varying the bias current between a first value below the critical current for the conductor means and a second value above the critical current. The non-linear device is a switching device comprising a switching element in the form of a superconducting film, a terminal for inputting a signal to the switching element, a terminal for outputting a signal from the switching element, and a circuit for applying a DC bias current to the switching element and for causing the DC bias current to vary between a first value below the critical current for the superconducting film and a second value above the critical current. The non-linear device is a square-law detector device comprising a thin-film superconductor, a terminal for coupling an RF signal to be detected to an input zone of the superconductor, a circuit for applying a DC bias current to the superconductor, the bias current being of a value to constrain the superconductor to operate in the quadratic portion of its resistance-current operating characteristic, and a circuit for obtaining a detected output signal from an output zone of the superconductor.

摘要： Described is a method of manufacturing a power-current cryotron having a layered gate-conductor structure which in the normal conducting state at the cryotron operating temperature has a free electron path length smaller than in the superconductor material of the cryotron. The method comprises steps of situating a pulverulent insulating material between a plurality of layers of superconductor material, and then compressing the layers together with the pulverulent insulating material therebetween to reduce the cross-sectional area of the cryotron. The superconductor material is selected from the group consisting of lead and niobium and the pulverulent insulating material is selected from magnesium oxide and aluminum oxide.
