Abstract

The quality superconducting YBa₂Cu₃O₇ films and YBa₂Cu₃O₇/NdBa₂Cu₃O₇ multilayered film structures have been grown by pulsed laser deposition on metallic templates with magnesium oxide (MgO) buffer layer grown by incline substrate deposition. Different supplementary buffer layers have been deposited between the superconductor and MgO buffer layer. This additional buffer layer reduces the crystal structure misalignment of the superconducting layers. The critical current density has been observed to be higher in the multilayered structures in comparison with the same thickness of monolayer YBa₂Cu₃O₇ films. The origin of this enhancement is the improved microstructure of the multilayered systems obtained.
