摘要

In order to achieve high irreversibility field (B-irr), we fabricated (Nd, Eu, Gd)Ba2Cu3Oy (NEGBCO) thin films by pulsed laser deposition (PLD) method and low temperature growth (LTG) technique. In the LTG-NEG-BCO films on MgO, critical current density (J(c)) at 77 K and magnetic field B = 5 T was 0.13 MA/cm(2) twice as high as that of PLD-NEGBCO/MgO and B-ir, at 77 K reached 11.8 T. Interestingly, the anomalous peaks on the J(c)-B and F-p-B (flux pinning force density F-p = J(c) x B) curves at 77 K and B = 4 T were observed on the LTG-NEGBCO/MgO films. From these results, we can consider that NEGBCO films are good candidates and LTG is an effective technique for improving superconducting properties.
