Abstract
We use spatially-resolved transport techniques to investigate the superconducting properties of single crystals La2−xBaxCuO4. We find a superconducting transition temperature Tcs associated with the ab-plane surface region which is considerably higher than the bulk Tc. The effect is pronounced in the region of charge carrier doping x with strong spin-charge stripe correlations, reaching Tcs=36 K or 1.64Tc.
