Quasiparticle dynamics and gap structure in Hg1223 investigated with femtosecond spectroscopy
J. Demsar, R. Hudej, J. Karpinski +2
Measurements of the temperature dependence of the quasiparticle (QP) dynamics in Hg1223 with femtosecond time-resolved optical spectroscopy are reported. From the temperature depen…
Critical currents, flux-creep activation energy and potential barriers for the vortex motion from the flux creep experiments
I. L. Landau, H. R. Ott
We present an experimental study of thermally activated flux creep in a superconducting ring-shaped epitaxial YBCO film as well as a new way of analyzing the experimental data. The…
Large oxygen-isotope effect in Sr_{0.4}K_{0.6}BiO_{3}: Evidence for phonon-mediated superconductivity
Guo-meng Zhao, K. Conder, M. Angst +6
Oxygen-isotope effect has been investigated in a recently discovered superconductor Sr_{0.4}K_{0.6}BiO_{3}. This compound has a distorted perovskite structure and becomes supercond…
Vortex melting and decoupling transitions in YBaCuO single crystals
X. G. Qiu, V. V. Moshchalkov, J. Karpinski
The vortex correlation along the c-axis in high quality single crystals of YBaCuO has been investigated as a function of temperature T in different magnetic field…
Strong vortex pinning in the low-temperature superconducting phase of (U_1-xTh_x)Be_13
Ana Celia Mota, Elisabeth Dumont, James L. Smith
We have found a sharp transition at T_c2=350 mK in the vortex creep rate of a single crystal of (U_1-xTh_x)Be_13 with T_c=523 mK (x=0.0275). For T<<T_c2, no creep of vortices is ob…
Transition into a low temperature superconducting phase of unconventional pinning in Sr_2RuO_4
A. C. Mota, E. Dumont, A. Amann +1
We have found a sharp transition in the vortex creep rates at a temperature T^\ast=0.05 T_c in a single crystal of Sr_2RuO_4 (T_{c}=1.03 K) by means of magnetic relaxation measurem…
Unconventional strong pinning in the low temperature phase of U_.9725Th_.0275Be_13
Elisabeth Dumont, Ana Celia Mota, James L. Smith
We investigated low field vortex dynamics in a single crystal of U_.9725Th_.0275Be_13. We found a sharp transition in the vortex creep rate at the lower transition temperature T_c2…
