抄録

Ba(Ti_0.85Zr_0.15)O₃ films were prepared at 973 K on (100)Pt/(100)MgO substrates by metalorganic chemical vapor deposition (MOCVD), and their dielectric properties were investigated. The dielectric constant (ε′) of the film changed depending on the ac electric field (E_ac) and frequency at temperatures below 400 K. The ε′ showed a broad maximum at a specific temperature (T_M) that decreased from 370 to 330 K with increasing E_ac from 0.15×10⁵ to 15×10⁵ V·m⁻¹. The film exhibited ferroelectric characteristics with remanent polarization (2P_r) of 3×10⁻² C·m⁻² and coercive field (2E_C) of 14×10⁵ V·m⁻¹.
