Book Description
"Attributing the normal state anisotropy in the heat transport to electrons in the Cu-O chains, the Lorenz number takes on its full Sommerfeld value i.e. $L = L sb0.$ Under this assumption, the phonon conduction is about the same in the superconducting and deoxygenated samples." --

Physical Properties of High Temperature Superconductors III
Author: Donald M. Ginsberg
Publisher: World Scientific
ISBN: 9789810208752
Category : Technology & Engineering
Languages : en
Pages : 644
Book Description
This volume brings the reader up to date on transport phenomena, including electrical and thermal conductivity and infrared properties. In addition, electron tunneling and the characteristics and applications of films are discussed; the preparation of the necessary samples has proceeded, and a sizeable body of reproducible data has become available. Pressure effects are also presented; considerable progress has been made in relating them to the crystallographic and electronic structure of high temperature superconductors. The preparation and characterization of bulk samples is also reviewed.

Heat Conduction in YBa2Cu3O7-delta

Book Description
"We have used thermal conductivity measurements at low temperature to probe the behavior of the unconventional superconductor YBa2Cu 3O7-delta (YBCO). Two aspects were investigated: (1) the in-plane anisotropy, studied in order to gain insight into the contribution of CuO chains, and (2) the effect of a magnetic field, investigated in order to explore the contribution of vortices. Our results on the low temperature thermal conductivity are in good quantitative agreement with the theory for a d-wave superconductor. We have found a very weak (or even negligible) anisotropy suggesting that the anisotropy could not simply be explained by mass tensor anisotropy or the plasma frequency anisotropy. The magnetic field studies revealed an increase in the residual linear term (kappa/ T as T → 0) with field, reflecting the contribution to the density of states from the extended quasiparticles due to their Doppler shift in the presence of vortices. These results are in good quantitative agreement with the theoretical predictions." --
