摘要：

GdBa2Cu3O7-delta (GdBCO) superconducting thin films, grown by Pulsed Laser Deposition (PLD) on MgO(100) single crystals are oxygen annealed using two different approaches: in-situ (oxygen annealing in PLD chamber) and ex-situ (oxygen annealing in tubular furnace). Their structural and transport properties are investigated in relation to annealing time (t(ann)) at 450 C-degrees. In-situ annealed GdBCO thin films require at least 15 min of annealing to achieve high in-field critical current densities (J(c)), while ex-situ annealed samples achieve high in-field J(c) already after 5 min of oxygen annealing at 450( degrees)C and 1 bar of oxygen pressure.
