GdBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> superconducting thin films, which were grown in situ on a (001) Zr(Y)O<sub>2</sub> substrate by DC magnetron sputtering with zero resistance transition temperature T<sub>c</sub> in the range 89.6-92.18 K, have been studied by X-ray diffraction experiments and pole figures. The relation between the a and b axes of GdBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> thin films and the in-plane lattice vectors of Zr(Y)O<sub>2</sub> has been obtained from the pole figures. It is found that there are two sorts of twins, 45 degrees and 90 degrees .
