Growth of twin-free b-oriented YBa2Cu3O7-x Films
Artikel i vetenskaplig tidskrift, 2015

YBa2Cu3O7 - x films of b orientation have been grown on the surface of (100)SrLaGaO4 crystal. It is demonstrated that the films pass to the superconducting state at a temperature of 89 K. In the nonsuper-conducting region, the film resistance decreases linearly with a decrease in temperature at a rate of 30 Omega per 100A degrees C. According to the X-ray diffraction data on the crystallographic structure of the YBa2Cu3O7 - x films, they are single-crystal and b-oriented. It is shown that the films contain no domains of other crystallographic orientations, including a-oriented domains. Therefore, the films are free of structural twins.
