Ba(Ti0.85Zr0.15)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 (Eac) and frequency at temperatures below 400 K. The ε′ showed a broad maximum at a specific temperature (TM) that decreased from 370 to 330K with increasing Eac from 0.15 × 105 to 15 × 105 V·m-1. The film exhibited ferroelectric characteristics with remanent polarization (2Pr) of 3 × 10-2 C·m-2 and coercive field (2E C) of 14 × 105V·m-1.
