    Abstract

    The resistivity of (Formula presented) (Formula presented) superlattices under magnetic fields was measured to investigate the flux pinning and anisotropic superconducting properties, where n is the number of the modulation layer. The fields applied were parallel to the ab plane and the c axis of the films. The resistivity under magnetic fields shows thermally activated behavior. A power law magnetic field dependence of (Formula presented) in YBCO/PBCO superlattices was observed. The (Formula presented) was observed to scale to a constant which increases linearly when the thickness of YBCO layers is increased and decreases linearly when the thickness of PBCO layers is increased. There exists both one-unit-cell YBCO and interlayer YBCO couplings in YBCO/PBCO superlattices. These couplings affect the coherence lengths.
