摘要：

The crystal structure of a-axis oriented YBa2Cu3O(x) (YBCO) films epitaxially grown on SrTiO3 (100) was investigated by ion channeling measurement. The lattice constant in the film plane was determined from the channeling angle through [110]/[103] angular scan measurements and a-axis lattice constant measured by the x-ray diffraction technique. The lattice constants of the a axis decreased with increasing film thickness, while the obtained lattice constants in the film plane revealed the close values to the lattice constant of the SrTiO3 substrate (3.905 angstrom). The relaxation of film strain was evaluated from the chi values estimated from [110]/[103] ion channeling. The chi values increased from 16.7% to 26.4% with increasing film thickness from 500 to 3500 angstrom. The effect of the strain relaxation on the superconductivity was confirmed for a-axis oriented YBCO films.
