A-axis oriented, electron-doped, Sr1-xLaxCuO 2 thin films were grown on LaAlO3 and YAlO3 substrates by magnetron sputtering. X-ray diffraction analysis revealed that in an as-grown state, the a-axis oriented films grew with the long-c phase, which is related to oxygen vacancies in the CuO2 planes, unlike the c-axis oriented films. Another feature of our a-axis oriented films is that the films contain 90° rotated domains from in-plane X-ray diffraction and planer transmission electron microscopy image. We discuss features of a-axis oriented films in terms of oxygen vacancies in the CuO2 planes.
