Abstract

We have prepared highly textured BiSrCaCuO thick films from mixtures of the oxides by a rapid melting process. Sample powders on (100)-MgO-substrates were melted within seconds and kept between 910 °C and 1050 °C for typically several minutes. The samples were then directly cooled to room temperature. The crystallization of Bi₂Sr₂CaCu₂O_x and the formation of a (001) - texture was observed in situ with a high-temperature X-ray diffractometer. Resistivity measurements showed the film to exhibit a T_c of 70 K. Subsequent annealing steps in air between 850 °C and 885 °C raised T_c to 85 K. The critical current density as inferred from magnetization measurements is at least 10³ A/cm². Morphology and composition of the films were investigated by scanning electron microscopy and electron diffraction.
