摘要：
The preparation of non c-axis oriented high T, superconductor films with longer coherence length is one of the key technologies toward realization of viable Josephson devices. For the first time. we have succeeded in growing in-plane aligned (119)Bi-2223 films on (110)SMO3 substrates by metalorganic chemical vapor deposition using a two-step growth temperature procedure. This procedure was found to be effective for orientation control and phase control in comparison with a fixed growth temperature procedure. As a result, superconducting properties were improved. The surface morphology observed by atomic force microscopy showed an in-plane aligned mountain-range shape, which strongly reflects the orientation relationship between the (119)Bi-2212 film and (110)SMO3 substrate.
