✦ Synopsis

Films of La 2 Zr 2 O 7 (=LZO) have been formed by chemical solution deposition technique (CSD) on new bi-axially textured Cu-Ni alloy tapes based on rolled constantan (Cu 55 Ni 45 ) Rabits. The precursor used was acetylacetonates treated in propionic acid (0.1-0.87 mol/l) and then deposited by spin-coating. The LZO film starts to crystallize above 850 • C, the film nucleates bi-axially textured on the substrate (with unit cell axis rotated 45 • from those of the substrate). The top part of the film is not textured even after long annealing time at 1100 • C, but the interfacial part is bi-axially textured. Thus, synthesis of bi-axially textured films on Cu 55 Ni 45 Rabits seems possible but more works are needed to optimize its properties.
