Title: Growth of twin-free b-oriented YBa{sub 2}Cu{sub 3}O{sub 7} {sub −x} films

YBa{sub 2}Cu{sub 3}O{sub 7−x} films of b orientation have been grown on the surface of (100)SrLaGaO{sub 4} 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 Ω per 100°C. According to the X-ray diffraction data on the crystallographic structure of the YBa{sub 2}Cu{sub 3}O{sub 7−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.
