    摘要

    We report here on the growth and transport properties of YBa2Cu3Oy/YxPr1-x,Ba 2Cu3Oy, superlattices. The YBa2Cu3Oy/YxPr1-xBa 2Cu3Oy [(YBCO/PBCO) for x = 0 and (YBCO/YPBCO) for x = 0.5] superlattices were grown in situ in an off-axis radio-frequency magnetron sputtering system. The superlattice structure of the samples was characterized by powder X-ray diffraction. Appearance of satellite diffraction peaks near the main (001) peaks confirms the superlattice structure. Resistivity measurements carried out under magnetic fields reveal thermal activated behaviour. Hall coefficients, RH, in mixed state show sign reversal and a diminishing of RH is observed when the thickness of the YPBCO layer is increased or the thickness of the YBCO layer is decreased. Angular dependence of the critical current density, Jc, in YBCO/PBCO superlattices shows a decoupled behaviour in the flux line dynamics as the coupling strength of the YBCO layer weakens.
