Paper Abstract

The preparation by a multi-target ablation method of films consisting in an attempt to texture CuO2 planes via the YBa2Cu3O7 structures, is investigated. All films are superconducting with onset temperatures ranging between 68 and 80 K. X-ray data show that the observed phases are both orthorhombic with c parameters close to YBCO-123 and 124. Infrared data indicate additional unknown phases which are not (or poorly) periodic, and likely inter-grown with periodic phases.
