Abstract

The temperature dependence of the absolute resistivity of YBCO, LSCO, BSCCO and CLBLCO thin films is reported, with special attention to the resistivity slope near Tc and under T*. The results are compared with the Lindner-Auerbach (LA) theoretical version of Homes’ law.

Good agreement between theory and experiment on all materials is achieved q=1.72(0.15), which is very close to the expected q=2   for Bosons. This finding indicates that the LA formula is self-consistent and supports the growing belief that cuprate superconductivity emerges from preformed cooper pairs.
