This publication includes all data on superconductive materials intercepted through March 1975. Dala on the bulk elements have been critically evaluated. and values on alloys. compounrl~. anti nth"T forms have been selected and condensed to indicate the probable value and spread of values observed. Prov"n non-superconductors have been noted. Conflict in data values has been noted. All data have been ,keyed to the literature in one or more of the tables. Special subdivisions are presented for $uperconduc· t~ve materials with organic constituents and for those based on semiconductive materials. The proper-tIes. ~res~nted are superconductive critical temperature, critical magnetic fields, material state and com· posItIOn mclu~ing crystal-structure type where noted, a key to thin-film forms, and the presence of thermodynamlc data (generally the electronic specific heat, 'Y, and Debye 6). High-magnetic·field superconductors are noted with listing 01' He,. H c ' He" and He, plus the temperature of observation T.~5

“…The apparent reason is that the jump in the electron heat capacity at T c in Nb is not very pronounced. 21 In addition, according to a semiquantitative approach proposed by Zaitlin, 22 the proximity effect in S / N bilayers further smears out any such jump with respect to the pure superconductor case. The latter fact is known from a theory of multiband ͑or anisotropic͒ superconductivity.…”

Time-resolved carrier dynamics and electron-phonon coupling strength in proximized weak ferromagnet-superconductor nanobilayers

et al. 2007

We present our femtosecond optical pump-probe studies of proximized ferromagnet-superconductor nanobilayers. The weak ferromagnetic nature of a thin NiCu film makes it possible to observe the dynamics of the nonequilibrium carriers through the near-surface optical reflectivity change measurements. The subpicosecond biexponential reflectivity decay has been identified as electron-phonon Debye and acoustic phonon relaxation times, and the decay of Debye phonons versus temperature dependence was used to evaluate the electronphonon coupling constants for both the pure Nb and proximized Nb/ NiCu heterostructures down to low temperatures. We have also demonstrated that the NiCu overlay on top of Nb dramatically reduced the slow, bolometric component of the photoresponse component, making such bilayers attractive for future radiation detector applications.

“…where C is the specific heat per unit volume at an intermediate temperature between that of the inner and outer surfaces, ∼3 K, of the order of 750 J/(m 3 K), 24 resulting in τ ∼ 0.36 ms. At high laser power (P abs > 60 mW), the temperature on the outer surface of the cavity plate increases above the lambdapoint. The Kapitza conductance of He I is reduced by about two orders of magnitude compared h K in He II, increasing τ to ∼30 ms.…”

An apparatus was developed to obtain, for the first time, 2D maps of the surface resistance of the inner surface of an operating superconducting radio-frequency niobium cavity by a low-temperature laser scanning microscopy technique. This allows identifying non-uniformities of the surface resistance with a spatial resolution of about one order of magnitude better than with earlier methods and surface resistance resolution of ~ 1  at 3.3 GHz. A signal-to-noise ratio of about 10 dB was obtained with 240 mW laser power and 1 Hz modulation frequency. The various components of the apparatus, the experimental procedure and results are discussed in detail in this contribution.
