    Notes: [Auszug] IN view of the well-known ‘stabilising’ effect of glycerin on soap solutions, it is not surprising to find that the elastic recoil of aqueous ammonium oleate—demonstrated by Hatschek at a Royal Institution discourse in 19271—is destroyed by a small addition of glycerin: the ...

    Notes: [Auszug] In his letter to Nature of June 28, p. 970, Mr. Lawrence has not, in my view, made the sandwich structure for soap films appear more likely, but has only discussed some necessary limitations to the layered arrangement that I suggested. One or two definite points may therefore be ...

    Laser ablation deposition of superconducting Bi-Sr-Ca-Cu-O thin films on zirconia-buffered crystalline quartz (1989)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 65 (1989), S. 4447-4449 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Thin films of Bi-Sr-Ca-Cu-O have been deposited on crystalline quartz substrates by laser ablation. Without a buffer layer, superconducting regions exist in the films as detected by magnetically modulated microwave absorption. However, with a 1000-A(ring) zirconia buffer layer, also deposited by laser ablation, continuous, superconducting thin films were obtained. It is shown that both annealing temperature and annealing time greatly affect the film quality.

    Microwave detection using granular Bi-Sr-Ca-Cu-O thin films (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 69 (1991), S. 2676-2678 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We report here results of our investigations of the nonbolometric mode of detection in granular Bi-Sr-Ca-Cu-O thin films. We find that both bolometric and nonbolometric modes appear in the same sample under mutually exclusive conditions: bolometric with light (633 nm) and nonbolometric with microwaves (9 GHz). Our measurements indicate that the nonbolometric mode of detection is more sensitive than the bolometric mode in our samples, a result which offers promise for application to microwave power measurement. Possible mechanisms for the nonbolometric mode are reviewed, and the concept of using a broadband spiral antenna directly coupled to the superconducting detector for microwave power sensing is briefly described.

    Modeling of pulsed laser etching of high-Tc superconductors (1990)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 68 (1990), S. 5273-5277 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Modeling of pulsed laser ablation has been applied to investigate the etching of high-Tc superconducting films of YBa2Cu3O7−δ and Bi2Sr2CaCu2O8. Calculations based on solutions to the one-dimensional heat equation and using parameters characteristic of the experiments indicate that diffusion does not play a major role and the dominant process is an evaporation mechanism taking place at the surface. Hence the ablation is modeled by solving the dynamical equations for a very thin heated layer in local equilibrium with the ablated material. With reasonable assumptions for the heat of evaporation (sublimation) and the phase equilibrium curve, the etch depth per pulse can be determined along with a number of other parameters. The results are in accord with observation.

    Magnetic properties of thin-film Ag+iron-oxide granular metals (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 4261-4263

    ISSN: 1089-7550

    Topics: Physics
    Notes: The magnetic properties of iron-oxide particulates dispersed in silver (prepared by rf diode sputtering silver and iron oxide over a wide composition range) have been investigated using the Mössbauer effect, electron microscopy, and vibrating sample magnetometry. The sputtered films are nanocrystalline mixtures of immiscible particles of the two constituents (even when only a very small amount of silver is present). At room temperature, the Mössbauer effect data show that for most compositions (even those with low silver content) the majority of the film is superparamagnetic, with the fraction of material in the superparamagnetic state increasing with increasing Ag content. Consistent with these results, very narrow hysteresis loops were observed. On decreasing the temperature to near 100 K, the fraction of material in the superparamagnetic state decreased and the magnetically ordered component increased. Electron diffraction patterns clearly showed the presence of polycrystalline Ag and Fe3 O4 in the films, but composition analysis (0.03 μm resolution) was unable to separate these regions.

    Superconducting thin films of Bi-Sr-Ca-Cu-O obtained by laser ablation processing (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 53 (1988), S. 321-323

    ISSN: 1077-3118

    Topics: Physics
    Notes: Thin films of Bi-Sr-Ca-Cu-O, deposited on (100) cubic zirconia by laser ablation from a bulk superconducting target of nominal composition BiSrCaCu2 Ox , have been investigated by dc resistance and magnetically modulated microwave absorption measurements. The latter technique reveals important features regarding the phase purity of superconducting samples that are masked in the dc resistance measurements. The superconducting behavior of the films, as a function of the substrate temperature during deposition and the post-deposition annealing conditions, is discussed.

    Notes: Abstract Samples having the nominal composition Bi0.7Pb0.3SrCaCu1.8O y , were prepared by a solid-state reaction and characterized by energy-dispersive x-ray microanalysis, resistivity measurements, and magnetically modulated microwave absorption (MAMMA). Longer annealing times resulted in more homogeneous samples having a single superconducting transition to zero resistance at 108 and 105 K at 0.1 and 1 mA, respectively. The MAMMA measurements clearly show differences in sample homogeneity with different annealing times.
