Abstract A correlation between the superfluid density n s(T) ∝ 1/λ2 ab(T) at low temperatures and the nanoscopic disorder in the a–b planes 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 the critical current density on temperature. These findings are consistent with a discovery of a nanodomain structure in the a–b planes of an optimally doped YBCO [J. Etheridge, Phil. Mag. A73, 643 (1996)].
