Global and Local Measures of the Intrinsic Josephson Coupling in Tl2Ba2CuO6

Autor: Tsvetkov, A. A., van der Marel, D., Moler, K. A., Kirtley, J. R., de Boer, J. L., Meetsma, A., Ren, Z. F., Koleshnikov, N., Dulic, D., Damascelli, A., Grueninger, M., Schuetzmann, J., van der Eb, J. W., Somal, H. S., Wang, J. H.

Publikováno v: Nature 395, 360 (1998)

The Intlerlayer Josephson coupling between the planes of Tl2Ba2CuO6 was determined using infrared spectroscopy and magnetic flux vortex imaging. These methods give a consistent value of $\omega_J$= 28 cm$^{-1}$ which, when combined with the condensat

Non-equilibrium Superconductivity and Quasiparticle Dynamics studied by Photo Induced Activation of Mm-Wave Absorption (PIAMA)

Autor: Feenstra, B. J., Schuetzmann, J., van der Marel, D., Pinaya, R. Pérez, Decroux, M.

Publikováno v: Phys. Rev. Lett. 79 (1997), 4890

We present a study of non-equilibrium superconductivity in DyBa2Cu3O7-d using photo induced activation of mm-wave absorption (PIAMA). We monitor the time evolution of the thin film transmissivity at 5 cm-1 subject to pulsed infrared radiation. In add

In-plane optical response of Bi2Sr2CuO6

Autor: Tsvetkov, A. A., Schuetzmann, J., van der Marel, D.

Publikováno v: Phys. Rev. B 55 (1997), 14152

We report on infrared reflectivity measurements of the $ab$-plane response of superconducting Bi$_2$Sr$_2$CuO$_6$ single crystals. The frequency dependent conductivity has a maximum near 700 cm$^{-1}$ at room temperature, which shifts to lower freque

Electrodynamical Properties of High Tc Superconductors Studied with Polarized Angle Resolved Infrared Spectroscopy

Autor: van der Marel, D., Schützmann, J., Somal, H. S., van der Eb, J. W.

Publikováno v: ISBN 981-02-2715-9 (1996), 357-370

Using infrared spectroscopy at grazing angle of incidence we study the electrodynamical properties of high temperature superconductors. We review some of our experiments where transverse polarized light is absorbed by longitudinal optical modes with

Grazing Incidence Infrared Reflectivity of La$_{1.85}$Sr$_{0.15}$CuO$_4$ and NbN

Autor: Somal, H. S., Feenstra, B. J., Schützmann, J., Kim, Jae Hoon, Barber, Z. H., Duijn, V. H. M., Hien, N. T., Menovsky, A. A., Palumbo, Mario, van der Marel, D.

Publikováno v: Phys. Rev. Lett. 26 (1996), 1525

Infrared reflectivity measurements, using p-polarized light at a grazing angle of incidence, show an increased sensitivity to the optical conductivity of highly reflecting superconducting materials. We demonstrate that when this measurement technique
