【 摘 要 】

We use spatially-resolved transport techniques to investigate the superconducting properties of single crystals La2-xBaxCuO4. We find a superconducting transition temperature T-cs associated with the ab-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-cs = 36 K or 1.64T(c)
