Fabrication by LPE and characterization of YBa/sub 2/Cu/sub 3/O/sub 7- delta / thin films on NdGaO/sub 3/ substrates

The superconducting c-axis oriented YBa/sub 2/Cu/sub 3/O/sub 7- delta / as well as bilayer films of PrBa/sub 2/Cu/sub 3/O/sub 7- delta //YBa/sub 2/Cu/sub 3/O/sub 7- delta / have been prepared by the liquid phase epitaxy (LPE) technique on
