Intermediate Annealing of YGdBCO Films by a CSD Method

Abstract:

Y0.9Gd0.1Ba2Cu3Oy films were prepared by the chemical solution deposition method. The effect of intermediate annealing on the phase, texture and superconducting properties of the films were evaluated. The results show that the intermediate annealing process is beneficial to achieve highly c-axis oriented YGdBCO film. The YGdBCO film prepared with intermediate annealing temperature of 400 oC has demonstrated high performance Jc (77 K, self field) = 2.4 MA/cm2.
