Penetration depth of electron-doped-infinite-layer Sr${}_{0.88}$La${}_{0.12}$CuO${}_{2+x}$ thin films

Abstract

The in-plane penetration depth of Sr${}_{0.88}$La${}_{0.12}$CuO${}_{2+x}$ thin films at various doping obtained from oxygen reduction has been measured, using AC susceptibility measurements. For the higher doping samples, the superfluid density deviates strongly from the s-wave behavior, suggesting, in analogy with other electron-doped cuprates, a contribution from a nodal hole pocket, or a small gap on the Fermi surface such as an anisotropic s-wave order parameter. The low value of the superfluid densities, likely due to a strong doping-induced disorder, places the superconducting transition of our samples in the phase-fluctuation regime.
