Effect of stripe ordering on the anisotropic superconductivity in La1.6−xNd0.4SrxCuO4 single crystals

The in-plane and out-of-plane resistivities of La1.6−xNd0.4SrxCuO4 single crystals were measured under magnetic fields up to 8 T. It was found that the superconducting transition temperature (Tconset) in the out-of-plane resistivity ρc is higher than that of the in-plane ρab, and the resistivity anisotropy ratio ρc/ρab increases with the enhancement of the static stripe order. This result indicates that the static stripe phase has different effects on the ab-plane and c-axis resistivities. From the study of the upper critical field, one can find that the anisotropy parameter and in-plane coherence length increase with the enhancement of static stripe phase.
