This paper reports on multilayer structures of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}-PrBa{sub 2}Cu{sub 3}O{sub 7{minus}y} prepared, using pulsed laser deposition, with the a-axis oriented normal to the surface of a variety of (001) substrates. Structural characterization of these films by X-ray diffraction (XRD), transmission electron microscopy (TEM) and helium ion beam channeling reveal a highly ordered microstructure similar, if not better, in quality to that obtained in the best c-axis oriented films. Studies of the surface morphology by scanning electron microscopy (SEM) show a very smooth surface with a total absence of the outgrowths commonly seen in c-axis oriented films.
