Abstract
(BFO) films of pure perovskite phase were deposited on (Pt), (LNO), and (BPO) substrates by rf magnetron sputtering. The BFO film was grown with random orientations on Pt whereas highly (100)-oriented and (111)-oriented ones were obtained on LNO and BPO, respectively. The influence of the bottom electrode on crystal growth, surface topography, leakage behavior, dielectric and ferroelectric properties was investigated. Twice remnant polarizations (2Pr) and coercive fields (2Ec) of the (100)-oriented BFO film were measured to be about and , while those of (111)-oriented ones were approximately and .Keywords
