Global and Local Measures of the Intrinsic Josephson Coupling in Tl2Ba2CuO6
A. A. Tsvetkov, D. van der Marel, K. A. Moler +12
The Intlerlayer Josephson coupling between the planes of Tl2Ba2CuO6 was determined using infrared spectroscopy and magnetic flux vortex imaging. These methods give a consistent val…
Experimental Test of the Inter-Layer Pairing Models for High-Tc Superconductivity Using Grazing Incidence Infrared Reflectometry
J. Schutzmann, H. S. Somal, A. A. Tsvetkov +7
From measurements of the far-infrared reflectivity at grazing angles of incidence with p-polarized light we determined the c-axis Josephson plasma frequencies of the single layer h…
Electrodynamical Properties of High Tc Superconductors Studied with Polarized Angle Resolved Infrared Spectroscopy
D. van der Marel, J. Schützmann, H. S. Somal +1
Using infrared spectroscopy at grazing angle of incidence we study the electrodynamical properties of high temperature superconductors. We review some of our experiments where tran…
Grazing Incidence Infrared Reflectivity of LaSrCuO and NbN
H. S. Somal, B. J. Feenstra, J. Schützmann +7
Infrared reflectivity measurements, using p-polarized light at a grazing angle of incidence, show an increased sensitivity to the optical conductivity of highly reflecting supercon…
Damping mechanism for the strongly renormalized -axis charge transport in high- cuprate superconductors
Jae H. Kim, H. S. Somal, D. van der Marel
We analyze the -axis infrared reflectivity of LaSrCuO single crystals. The plasma edge near 6 meV, observed below , is due to Cooper-pair tunneling. T…
