Abstract
A correlation between the superfluid density n(s)(T) proportional to 1/lamb da (2)(ab) (T) at low temperatures and the nanoscopic disorder in the a-b p lanes of YBCO thin films has been revealed. It has been found that a degree of this disorder can be determined from the two-component dependence of th e critical current density on temperature. These findings are consistent wi th a discovery of a nanodomain structure in the a-b planes of an optimally doped YBCO [J. Etheridge, Phil. Mag. A73, 643 (1996)].
