Abstract

We use spatially-resolved transport techniques to investigate the superconducting properties of single crystals ${La}_{2 - x} {Ba}_{x} {CuO}_{4}$ . We find a superconducting transition temperature $T_{c s}$ associated with the $a b$ -plane surface region which is considerably higher than the bulk $T_{c}$ . The effect is pronounced in the region of charge carrier doping $x$ with strong spin-charge stripe correlations, reaching $T_{c s} = 36$ K or $1.64 T_{c}$ .
