    In the framework of the search for new materials for sputter coated superconducting rf cavities for particle accelerators, an innovative method to measure the rf properties of superconducting films, based on an inverted microstrip ring resonator technique, is presented. Test measurements on well characterized Nb sputtered films show excellent agreement with the Bardeen, Cooper and Schrieffer theory and prove the good resolution of the method. New results obtained by this technique on the surface impedance of (NbTi)N reactively sputtered films, including the temperature dependence and the rf field amplitude dependence of the surface resistance and the temperature dependence of the magnetic field penetration depth, are then presented and discussed.

    The superconducting properties of spin-glass superconducting multilayers made of Nb (superconducting) and CuMn (spin glass) have been studied. The superconducting critical temperature Tc of the multilayers was strongly dependent on the thickness of the spin-glass layers. The Radovic et al. theory [Phys. Rev. B 44, 759 (1991)], which foresees a phase difference 0≤φ≤π between neighboring superconducting layers, has given a qualitative description of these experimental data. The parallel and perpendicular critical magnetic-field measurements have shown many interesting effects related to the reduced dimensionality of the samples. © 1995 American Institute of Physics.

    The electrical transport properties of Bi2Sr2Ca1Cu2O8+x thin films have been measured in the temperature range from 20 to 50 K and in external magnetic fields up to 4 T. The dependence of the normalized pinning force f=Fp/Fp,max on the reduced magnetic field h=H/H* (H* is the irreversibility field) exhibits a scaling law behavior, indicating that a single pinning mechanism is present in the investigated temperature range. The Fp(H) curves were analyzed within the framework of the classical Anderson–Kim theory of flux creep, taking into consideration the nonlinear current dependence of the pinning energy U and its dependence on the temperature T, the magnetic field H, and the current density J. Under these assumptions a generalized formula for Fp was obtained which, assuming a suitable U(J) dependence, was able to explain the f(h) curve in the observed temperature range. © 1996 American Institute of Physics.

    Using a ring microstrip resonator technique, the surface impedance of V3Si sputtered films has been measured as a function of temperature and dc and rf field amplitude. The results are analyzed in terms of the Bardeen–Cooper–Schrieffer theory and of a grain-boundary Josephson model, and discussed in the framework of the possible application of V3Si as a thin-film coating of superconducting rf cavities for particle accelerators. © 1995 American Institute of Physics.

    We developed an in situ micropatterning process for Bi2Sr2Ca1Cu2O8+x thin films using the large volumetric increase of refractory metals such as Nb, V, and Ta, during the hard regime of oxidation. After the lift-off procedure, our films showed nonreduced critical currents and temperatures. This technique is particularly suitable for multilayer in situ lithographic process. © 1995 American Institute of Physics.

    Abstract: We investigated the vortex lattice ordering induced by an applied current in thick (700-900 nm) Mo-Re films with strong pinning. Measurements of I-V characteristics as a function of field and at different temperatures were carried out. We found that, as in the case of weakly pinning amorphous samples, dynamic ordering can occur only if the size of the vortex correlated region is at least two times the intervortex distance.

    Summary We realized BSCCO thin films withT c(R=0)=88 K using the Molecular Beam Epitaxy (MBE) technique. The stoichiometric control is reached by a multilayer deposition technique in which Ca−Cu−Sr−Bi are sequentially deposited using the two effusive cells and the two e-guns present in the system. EDS and X-ray analyses are used to cross-check the obtained results, after theex situ in air annealing. The recent acquisition of an atomic oxygen source will allow in the close future the completelyin situ realization of BSCCO thin films.

    Notes:
    Abstract. The influence of the finite dimensions of superconducting metallic multilayers on H-T phase diagram is studied. It is established that the geometrical symmetry of the samples determines crucially the $H_{c2\vert \vert}(T)$ dependencies. For samples where the symmetry plane is in the middle of the superconducting layer the $H_{c2\vert \vert}$ values are, for temperatures close to T c , larger than the $H_{c2\vert \vert}$ values of the samples for which the symmetry plane lies in the middle of the normal layer. The results are analysed on the basis of the Ginzburg-Landau approach and are explained by considering the different symmetry of the wave function describing the system. The experimental results are in good agreement with the elaborated model, which takes into account the actual symmetry of the samples.

    Abstract. We have investigated, in the framework of proximity effect theory, the interface transparency ${\cal T}$ of superconducting/normal metal layered systems which consist of Nb and high paramagnetic Pd deposited by dc magnetron sputtering. The obtained ${\cal T}$ value is relatively high, as expected by theoretical arguments. This leads to a large value of the ratio $d_{s}^{cr}/ \xi_{s}$ although Pd does not exhibit any magnetic ordering.

    Abstract Critical current density vs. temperature curves and I–V characteristics have been measured onc-axis-oriented BSCCO thin films. The experimental data have been described in terms of flux creep effects. Although the films are not single phase and carry a slightly lower critical current density with respect to those of BSCCO single crystals, the measurements point to the presence of flux thermally activated phenomena with a pinning potentialU 0 of about 25 meV.
