Superlattices of one unit-cell thick YBCO layers with (PrxY1-x)BCO were fabricated as a model system to study the effects of magnetic coupling on anisotropic pinning behaviors in high-Tc superconductors. A 3D to 2D crossover was observed when the sample was transformed from an S/S' to an A/N structure by increasing the temperature without changing the microscopic structure. The results demonstrate the significance of the dimensionality to the flux pinning in these materials with layered structures.
