Abstract: Crystal orientation of BiSrCaCuO(11n) films depends on off-angles of vicinal SrTiO3(110) surfaces. Surfaces of SrTiO3(110) were cut 2°, 5° and 10° toward the [100] direction, and BiSrCaCuO thin films, which had a 2212 phase, were formed on these vicinal surfaces by RF magnetron sputtering. C-axes almost parallel to the [100] and [010] directions of the substrate were observed when the 2°- and 10°-off substrates were used, but only the c-axis parallel to the [010] was observed when the 5°-off substrate was used. These results suggest that there is an appropriate off-angle to obtain BiSrCaCuO thin films with the c-axis almost parallel to [010] only.
