The preparation by a multi-target ablation method of new structures consisting in CU02 planes textured via the YBa2Cu307 structure, is investigated. All films are superconducting. X ray data show that a new phase with more than two c0n.sec~tive conductive planes might have been obtained. The onset temperatures which stay between 68 and 80 K mdlcate a probable underdoping.
