| Abstract: | YBa2Cu3O7 films with the CuO plane tilted to the surface have been grown on SrTiO3 crystalline substrates by pulsed laser deposition. This tilt was obtained by rotating the film lattice with respect to the substrate surface around its 110] axis oriented parallel to the surface. The zero tilt of the CuO plane was implemented at the orientation of the SrTiO3 crystal surface parallel to the (100) plane. The rotation angles were varied in the range from 0° to 70°. It is found that, being tilted at any angle, the CuO planes of the film remain parallel to one or several crystallographic planes of the (100)-type substrate. In the range of tilt angles from 0° to 49°, the film has a single-crystal structure. Above 49° the film is transformed into a three-domain texture and its surface roughness sharply increases. |
