Abstract High-T c superconducting films of YBa2Cu3Ox on sapphire with an additional buffer layer of strontium titanate (actually, on heterostructures (100)SrTiO3/(001)YBa2Cu3Ox/(100)CeO2/(1102)Al2O3) are obtained by laser deposition, and their superconducting characteristics are investigated. It is shown that that buffering the sapphire by a strontium titanate film can raise the critical temperature of the YBa2Cu3Ox films by two degrees and give a severalfold increase in the critical current density.
