Abstract
High superconducting B S CaC (BSCCO2212) films were prepared by a metallorganic decomposition (MOD) method. The metal organic solution of BSCCO2212 was spin-coated on MgO (100) substrates at 3000 rpm for 1 min. To achieve a high critical current density, we controlled heat-treatment conditions and atmosphere. The films were annealed at temperature 75 ∼ 80 in or air. We obtained c-axis orientated BSCCO thin films on MgO substrates. The annealed sample at 77 with showed the critical temperature about 77 K and critical current denstity of 1.19 10 A/ about 13 K.K.K.
