Abstract

Contributions of superconducting fluctuations and regular part to the temperature dependence of normal state resistance (Ra,) has been studied on two YBCO single crystals with close oxygen content. Analysis of the data using conventional models of "fluctuation" conductivity has shown that the coherence length εo and phase relaxation time fo take unphysical values if the upper boundary of the temperature interval increases up to 1.5To. The fitting becomes rather good if we take into account the contribution to the regular part of Ra, which is due to electron-spin interaction.
