Abstract
BaTi2O5 film was prepared on MgO (100) substrate by laser ablation, and the structure and electric
property of the film were investigated. The film was b-axis oriented and epitaxially grown on the
substrate along two in-plane directions with the a-axes ([100]-orientation) perpendicular to each
other. The b-axis oriented BaTi2O5 film exhibited a sharp permittivity maximum (~ 2000) and had
a high Curie temperature (750 K). The electrical conductivity increased with temperature and
showed the Arrhenius relationship having an activation energy of 1.25 eV.
