Abstract

BaTiO₃ (BT) ceramics were prepared by electrophoretic deposition (EPD) or slip casting (SC) in a high magnetic field (HM) of 12 T using single-domain or multi-domain BT particles. The {110}-oriented BT ceramics with a Lotgering factor of 25% were prepared by HM-EPD of the single-domain BT particles, while no texture was observed for the BT ceramics prepared by HM-SC of the single-domain BT particles and for the BT ceramics prepared using the multi-domain BT particles regardless of the preparation methods. These results were discussed with factors that reduced the magnetic anisotropy of the BT particles.
