Abstract(in English) We have prepared Bi_2Sr_2CaCu_2O_x (Bi-2212) thin films on MgO (100) substrate by a metal-organic decomposition (MOD) method for high-frequency applications. The lattice mismatching rate in ab-plane between Bi-2212 and MgO is 8.9%, and it was reported that the in-plane-orientation had small fractions of rotation angle φ~ ±12 deg. in addition to a cube-on-cube textured growth. In order to overcome the problem of these fractions, we fabricated a SrTiO_3 (STO) buffer layer on MgO substrate by MOD method because the lattice mismatching rate between STO and Bi-2212 is 1.8%. The in-plane rotation angle of Bi-2212 fabricated on STO buffer layer / MgO substrate evaluated by an X-ray diffraction method showed all cube-on-cube textured growth without any fractions.
