Vortex correlation in the region of the depinning transition has been studied in twinned YBa2Cu3O7-delta single crystals with T-c approximate to 80 K. Transport properties along the e-axis were performed in magnetic fields parallel to the ab-plane, using the pseudo flux-transformer method. By rotating the sample around the c-axis, both longitudinal and transverse vortex correlation could be studied. Compared to optimally doped samples, transverse vortex velocity correlation was enhanced at high fields, while longitudinal correlation remained qualitatively the same.
