SUMMARY

The Ginzburg-Landau (G-L) parameter for YBCO (Yttrium Barium Copper Oxide) exhibits significant anisotropy, differing along the ab-plane and the c-axis. A key reference detailing the G-L parameter derived from magnetization curves can be found on page 789 of a specific academic text. This reference provides essential insights into the coherence length and penetration depth ratios relevant to YBCO's superconducting properties.

PREREQUISITES
  • Understanding of superconductivity principles
  • Familiarity with Ginzburg-Landau theory
  • Knowledge of anisotropic materials
  • Experience with magnetization curve analysis
NEXT STEPS
  • Research the Ginzburg-Landau parameter calculations for anisotropic superconductors
  • Study the magnetization curves of YBCO in detail
  • Explore the implications of coherence length and penetration depth in superconductivity
  • Review literature on YBCO's superconducting properties and applications
USEFUL FOR

Physicists, materials scientists, and researchers focused on superconductivity, particularly those studying YBCO and its anisotropic properties.

Can anyone provide a good reference which gives the G-L parameter for YBCO (a) along the ab-plane of the sample and (b) along the c-axis?

I've been to the depths of Google Scholar and back and found nothing, so any help would be much appreciated. :)

Typically YBCO is highly anisotropic parallel and perpendicular to the planes in terms of the G-L (coherence length / penetration ratio).
For the details derived from magnetization curves see page 789 here ; entire last paragraph:
