Correlation between superfluid density and Tc of underdoped YBa2Cu3O6+x near the superconductor-insulator transition
We report measurements of the ab-plane superfluid density Ns (magnetic
penetration depth, \lambda) of severely underdoped films of YBa2Cu3O6+x, with
Tc's from 6 to 50 K. Tc is not proportional to Ns(0); instead, we find Tc ~
Ns^{1/2.3 +/- 0.4}. At the lowest dopings, Tc is as much as 5 times larger than
the upper limit set by the KTB transition temperature of individual CuO2
bilayers.Comment: 4 pages, 2 figures, Submitted to Phys. Rev. Let
