Uemura Plot as a Certificate of Two-dimensional Character of Superconducting Transition for Quasi-two-dimensional HTS
Abstract
Description
With using general properties of superconducting state for 2D systems the universal temperature dependence of the penetration length is found out for quasi-2D HTS, that leads to Uemura plot and evidences about 2D character of superconducting transition. It is shown that from the measurements of c-axis resistivity and of the penetration length the value of the interval of 3D superconducting fluctuations can be determined.
