Abstract
Artificially stacked structures of [(infinite layer CaCuO2)k/(superconducting (Cu, C)Ba2CuOx:(Cu, C)-1201)l]m were fabricated on SrCuO2 buffer layer by means of sequential deposition of each block using pulsed laser deposition. Smooth and epitaxial growth all over the deposition cycles of (Cu, C)-1201 and CaCuO2 were confirmed by streak patterns of in situ RHEED. In comparison with (Cu, C)-1201 single layer films, the artificial stacking resulted in a rise of superconducting properties, Tc-onset and Tc(ρ=0) up to 95 K and 65 K, respectively.
