Deposition on Vicinal Substrates for Domain Selection in YBa[sub 2]Cu[sub 3]O[sub 7] Films.

(110) and (103) YBa[sub 2]Cu[sub 3]O[sub 7] films have been grown onto exact and vicinal (110) SrTiO[sub 3] substrates, and on vicinal (110) MgO substrates with a SrTiO[sub 3] buffer layer. The samples are carefully characterised by reciprocal space mapping with x-ray diffraction, in order to investigate the features of the typical double domain of (110) and (103) YBa[sub 2]Cu[sub 3]O[sub 7] structure. It is demonstrated that vicinal cut substrates allow to select one film/substrate epitaxial relation. The growth properties of these thin films deposited on vicinal surfaces are discussed.
