C-axis josephson tunneling between YBa2Cu3O7 − δ and Pb: Direct evidence for mixed order parameter symmetry in a high- Tc superconductor
(1997)C-axis Josephson tunneling experiments in which a conventional superconductor (Pb) is deposited across a single twin boundary of a YBa2Cu3O7 − δ (YBCO) crystal. We measure the critical current as a function of the magnitude ...

Experimental determination of the absolute temperature modulation in photothermal microscopy of Y1Ba2Cu3O7 crystals
(1997)We present a technique to experimentally determine the value of the temperature perturbation ST in photothermal microscopy. Knowledge of δT is necessary for proper analysis of the differential optical reflectivity (∂R/∂T) ...

The nanostructure, wear and corrosion performance of arc-evaporated CrBxNy nanocomposite coatings
(2009)The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS ...

Novel multibit magnetic tagging techniques for high-throughput multiplexed chemical analysis
(2009)In this paper, we have investigated a remote encoding/decoding method of micrometer-sized multibit magnetic tags and demonstrated the operation of magnetic digital tags to discuss the practical issues which arise. The tags ...

Progress in photothermal microscopy of YBa2Cu3O7-x
(1998)We present recent differential optical reflectivity (DOR) measurements obtained at 633 nm (2.OeV), 780 nm (1.6eV), 1064 nm (1.16eV), and 1310nm (0.95 eV). We discuss calibration techniques which can correct for variations ...

Study of optical fiber structures using atomic force microscopy and scanning near-field optical microscopy
(1996)Atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM) were used to study optical fiber structures. The refractive index profile of fiber was disclosed by surface topography of etched fiber endface ...
