Chemical solution deposition of textured BaTiO_3 buffer layers on cube textured Ni-tapes fabricated from commercially available nickel

摘要

Barium titanate buffer layers were successfully applied to cube textured Ni-tapes fabricated from commercially available nickel by a chemical solution deposition route. Barium acetate solutions in anhydrous acetic acid were mixed with bis(pentane-2,4-dionato)-titanium(IV)-oxide dissolved in methanol. A slight excess of acetic acid anhydride assured the anhydrous medium. The precursor solution was spin-coated to the Ni-substrate. Heat treatment at 1 000°C under a reducing atmosphere (Ar + 6.5 vol-% H_2) resulted in dense c-axis oriented, a-b in-plane aligned buffer layers.
