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.
