Notes:
The thin Bi(Pb)-Sr-Ca-Cu-O film composed of the high Tc phase has been successfully made by the thermal decomposition method using an organic acid salt, which is spread on the MgO(100) substrate by the spin-coat method. A preannealing process before a final annealing is added to the usual film preparation in order to prevent the metallic compounds in the salt from diverging to the atmosphere. The film obtained here has a flatter and smoother surface, and a higher zero-resistivity temperature Tc0 (=107.0 K) than those of the films without the preannealing process. However, the homogeneity of the film seems to be slightly insufficient as the onset critical temperature of the real part of a complex susceptibility is about 3 K larger than Tc0.
