Abstract Epitaxial Bi2Sr2−xLa x Cu1O6+δ thin films were grown on vicinal substrates by magnetron sputtering. The growth mode and the superconductivity of the thin films were studied. The films were deposited on 5–7° misoriented (100) SrTiO3 (STO). The surface of misoriented substrate is tilted to the 〈111〉 azimuth. The topographies of the Bi-2201 films show strip-like shapes. The transmission electron microscopy (TEM) study revealed that the films grew with very good in-plane alignments which were comparable to those of single crystals. Both of the temperature dependence of the a- and c-axis resistivities were studied under magnetic fields. The corresponding anisotropic activation energies and upper critical magnetic fields were investigated.
