    Notes:
    We have made measurements of the T dependence of microwave absorption (at 22.7 GHz) in films of Y1Ba2Cu3Ox on SrTiO3 and LaGaO3 substrates. The superconducting transition temperatures were near 90 K. The film on SrTiO3 had predominantly c axis normal to the film, while the film on LaGaO3 was partially a axis oriented. The microwave losses L for both films followed the temperature dependence given by L∝t/(square root of)1−t, with t=T/Tc. In the macroscopic theory of Ginzburg–Landau, this expression is proportional to the number of normal electrons within a penetration depth of the surface of the film, provided (1−t)(very-much-less-than)1. However, we find that the above expression fits the data well for a wide range of T.

    Notes:
    We demonstrate that lanthanum gallate (LaGaO3) has considerable potential as an electronic substrate material for high-temperature superconducting films. It provides a good lattice and thermal expansion match to YBa2Cu3O7−x, can be grown in large crystal sizes, is compatible with high-temperature film processing, and has a reasonably low dielectric constant (ε(approximately-equal-to)25) and low dielectric losses. Epitaxial YBa2Cu3O7−x films grown on LaGaO3 single-crystal substrates by three techniques have zero resistance between 87 and 91 K.

    Notes:
    A flexible combination of superconducting integrated circuits was used to construct a low-temperature magneto-optic microsusceptometer utilizing a dc superconducting quantum inteference device (SQUID) detector operating near the quantum limit (coupled energy sensitivity of 1.7(h-dash-bar)). Miniature pick-up loop assemblies on transparent substrates were joined by superconducting interchip connections to a thin-film dc SQUID, which is in turn read out by a second dc SQUID connected to room-temperature electronics. Measurements on an 8.5-μm-diam titanium dot evaporated directly into the pick-up loop demonstrate a spin sensitivity of ∼103 spins/(Hz)1/2 at T=290 mK.

    Notes:
    We have fabricated and characterized the noise performance of well-coupled Nb-Pb alloy edge junction dc superconducting quantum interference devices (SQUIDs) with a resistively shunted inductance. The extra damping resistor removes the resonances in the current-voltage characteristics resulting in a very low value of the extrinsic energy sensitivity in flux-locked-loop operation. Numerical simulations, with the junction capacitance included, indicate that the damping resistance does not degrade noise performance until it is significantly less than the junction-shunting resistance. We also tested different SQUID designs and demonstrated that a large SQUID inductance, proposed earlier to be desirable when resistively shunted, can seriously affect the low-frequency flux noise.

    Notes:
    We report a simple, single-target magnetron sputtering process for films of high-temperature superconductors involving an off-axis sputtering geometry. The process lends itself both to film growth with high-temperature post-anneals and to low-temperature in situ film growth. The post-anneal process routinely yields YBa2Cu3O7−x films on SrTiO3 substrates that are fully superconducting at 86–89 K. Current densities at 77 K range from 104 to 8×105 A/cm2. A single-level superconducting quantum interference device (dc SQUID), made by photolithographically patterning a low current density film, has a flux noise level at 77 K of 3×10−4 Φ0/(Hz)1/2 at 20 Hz, dominated by low-frequency noise associated with flux motion in the film.

    Notes:
    We have studied in detail the current-voltage (I-V) curves of dc SQUIDs in the presence of rf fields in the frequency range 2–18 GHz. Strong voltage locking at half-integral as well as the usual integral Shapiro step spacing is observed when the applied dc-magnetic flux is close to half-integral numbers of flux quanta. Numerical simulations are in excellent agreement with the experimental I-V curves. The half-integral steps are found to be associated with the flip-flop between two adjacent fluxoid states of the SQUID synchronized to the rf field.

    Notes:
    A multichannel rail-gap switch, triggered by ultraviolet radiation sources and capable of high repetition rate, long-life operation is described. The device will switch 30-kV, 30-kA, 80-ns pulses at pulse rates up to 100 Hz. Gas consumption is low (1-SLPM air), and under optimum conditions, switch inductance and jitter are 14 nH and ±5 ns, respectively. Prefire statistics and erosion rates have been studied.

    Notes:
    We report a wet etch process for selective patterning or removing gold (Au) layers on top of high Tc YBa2Cu3O7 (YBCO) thin-film structures. As an etchant for Au, an aqueous solution of potassium iodide (KI) and iodide (I) was chosen. This etchant does not degrade YBCO or any commonly used substrate materials (SrTiO3, MgO, zirconia, and NdGaO3). This KI and I solution gives convenient etch rates of 200–300 A(ring)/min and easily stops on the YBCO due to its high selectivity. Using this wet chemical etching process, we have fabricated structures with better than 1 μm resolution. We have found this etchant to be very useful for secondary electron microscopy analysis of high Tc device structures.

    Notes:
    We describe a wet etch process for patterning insulators suitable for multilayer epitaxial highTc superconductor-insulator-superconductor structures down to micronmeter-scale dimensions. A solution of 7% HF in water gives convenient etch rates for SrTiO3 and MgO insulators (about 1500 A(ring)/min for single crystals), and easily stops on thin high Tc superconducting layers, due to the high selectivity of this etchant between these insulators and the cuprate superconductors. Using entirely wet etching patterning processes, we have fabricated 5-turn (20-turn) coils with zero resistance at 89 K (79 K) and critical currents at 77 K of 2.5 mA (6 μA).
