Abstract

The authors report the fabrication of grain-aligned [Ca₂CoO _3-δ]_0.62CoO₂ (Ca349) thick films and a multilayered thermoelectric unicouple of Ca349 and Ca_0.9La _0.1MnO_3-δ (Mn113) using electrophoretic deposition (EPD) and magnetic alignment methods. Strongly c-axis-oriented Ca349 thick films were obtained by EPD performed under magnetic fields. In addition, the c axis of grains was found to always align parallel to the direction of field, independently of the EPD cell configuration. The required conditions for magnetic grain alignment of fine Ca349 powders were quantitatively discussed based on magnetization anisotropy. An α-Al₂O ₃/Mn113/α-Al₂O₃/Ca349/α-Al ₂O₃ multilayered thick film was successfully developed.
