    Abstract

    This work measures the resistivity and Hall coefficient (Formula presented) for a series of YBa(Formula presented) (YBCO/PBCO) superlattices. The Hall coefficient (Formula presented) systematically varies with different thicknesses of YBCO or PBCO layers. The Hall number decreases with a decreasing thickness of YBCO layers or increasing thickness of PBCO layers. We investigate the temperature dependence of the Hall angle in YBCO/PBCO superlattices as well. The cotangent Hall angle is also observed to follow a universal (Formula presented) dependence in all superlattices, i.e., (Formula presented) where both (Formula presented) and (Formula presented) change with the layer thickness. From the results presented herein, we believe that the reduction in carrier density, caused by the magnetic scattering effects and hole filling which occur near the interface, leads to the depression of (Formula presented) in the YBCO/PBCO superlattice.
