摘要：

The fabrication of Tl2Ba2CaCu2O8 (2212) superconductive thallium oxide thin films by a multitarget sputtering process has been performed, using Ba2-xCaxCuO3, Ca2CuO3, Cu and Tl targets. This deposition method allows preparation of homogeneous films on 2-in (100) MgO substrates. After an annealing treatment under thallium oxide pressure, films with 2212 composition exhibit zero resistance above 105 K, with a good reproducibility. The microstructure of these films has been studied by transmission electron microscopy.
