Abstract

Polycrystalline superconducting thin films of Bi₂Sr₂CaCu₂O_8+δ have been successfully grown on MgO [100] and polycrystalline Al₂O₃ substrates via liquid phase epitaxy from a Bi-2201 melt with excess Ca and Cu ions. The optimum annealing temperature in air of the grown films was found to be between 820−830°C. The best film obtained was grown on Al₂O₃ with a superconducting transition temperature, T_c ≈ 75K.
