Title Surface superconductivity and Kapitza resistance Type (up) Conference Article
Year 1980 Publication Phonon Scattering in Condensed Matter Abbreviated Journal
Volume Issue Pages 199-202
Keywords
Abstract It has been shown1 that surface superconductivity can be used as a localized thermomether to study the temperature close to an interface through which heat is being transported. Knowledge of the temperature profile in the interface region provides evidence which any theory of the heat transport mechanism must take into account. For interfaces between pure lead and HeII we have previously found1 clear differences between extrapolated surface temperatures Tk. and Tm, measured within some 1000Ã… of the interface using a superconducting thermometer. (The reader is refered to ref.1 for details on the experimental method).

Title Structural relaxation: low temperature properties Type (up) Conference Article
Year 1984 Publication Abbreviated Journal
Volume Issue Pages 269
Keywords ALLOY SYSTEMS, AMORPHOUS STATE, COPPER ALLOYS, SUPERCONDUCTING COMPOSITES, TEMPERATURE DEPENDENCE, ZIRCONIUM BASE ALLOYS
Abstract We discuss the changes in transport and superconducting properties of amorphous Zr70Cu30,

induced by thermal relaxation The experimental results are used to investigate the

relation between the microscopic parameters and the observed physical properties It

is shown that the density of eletronic states determines the shift Tc as well as the

variation of the electrical resistivity It is necessary to assume strong hybridization

between s and d bands to understand the eletrodynamic response of the superconductor

Title The true pinning force range in Bi2Sr2CaCu2O8 single crystals at low temperatures Type (up) Journal Article
Year 2004 Publication Physica C Abbreviated Journal
Volume 408-410 Issue Pages 531-532
Keywords
Abstract We study the effective profile of the pinning potential well in Bi$2$Sr$2$CaCu$_2$O8+δ single crystals using transverse ac magnetic susceptibility. The results show that the harmonic approximation for the potential well (linear regime) is valid up to vortex displacements $r\simeqξ$, where ξ, is the coherence length. In spite of this, it is necessary to induce displacements of the vortex structure much larger than ξ to depin it from its potential. This is shown to take place even in the single vortex limit.

Title Imaging the structure of the interface between symmetries interconnected by a discontinuous transition Type (up) Journal Article
Year 2003 Publication Solid State Communications Abbreviated Journal Solid State Commun.
Volume 128 Issue 3-4 Pages 51-55
Keywords
Abstract We have been able to observe with single particle resolution the interface between two structural symmetries that cannot be interconnected by a continuous transition. By means of an engineered 2D potential that pins the extremity of vortex strings a square symmetry was imposed at the surface of a 3D vortex solid. Using the Bitter decoration technique and on account of the continuous vortex symmetry, we visualize how the induced structure transforms along the vortex direction before changing into the expected hexagonal structure at a finite distance from the surface.

Title Magnetic state modification induced by superconducting response in ferromagnet/superconductor Nb/Co superlattices Type (up) Journal Article
Year 2008 Publication PHYSICAL REVIEW B Abbreviated Journal
Volume 77 Issue 10 Pages
Keywords
Abstract Magnetization measurements in superconductor/ferromagnet Nb/Co superlattices show a complex behavior as a function of temperature, applied field, and sample history. Based on a simple model, it is shown that this behavior is due to an interplay between the superconductor magnetization temperature dependence, the ferromagnet magnetization time dependence, and the stray fields of both materials. It is also shown that the magnetic state of the Co layers is modified by the Nb superconducting response, implying that the problem of a superconductor/ferromagnetic heterogeneous sample has to be solved in a self-consistent manner.

Title Superconducting behaviour of Nb/Co superlattices Type (up) Journal Article
Year 2007 Publication Applied Surface Science Abbreviated Journal Appl. Surf. Sci.
Volume 254 Issue 1 Pages 375-377
Keywords
Abstract We study the superconducting and magnetic behaviour of Nb/Co superlattices, for superconducting Nb layer thickness of 44 nm and Co layer thickness less than 1 nm. In this limit no ferromagnetism is observed for Co. The superlattice behaves as independent superconducting Nb layers. We obtain the penetration depth and superconducting gap of the material, and analyze the results in terms of microscopic models and theories. (C) 2007 Elsevier B.V. All rights reserved.
