Abstract

Polycrystalline BiFeO₃ thick films were prepared on Pt/TiO₂/SiO₂/Si substates by using magnetic field-assisted pulsed laser deposition. Columnar BiFeO₃ thick films were successfully obtained with a thickness of 1.8 μm, owing to an oblique incoming flux and high deposition rate by the confinement of the plume under a magnetic field. In the columnar BiFeO₃ thick films, a saturated P-E hysteresis loop was obtained at RT, and the remanent polarization (P _r) and coercive field (E _c) were 42 μC cm⁻² and 380 kV cm⁻¹, respectively. Also, the piezoelectric response measured by atomic force microscopy showed a butterfly-shaped curve, and the piezoelectric d ₃₃ coefficient was about 50 pm V⁻¹.

磁场辅助脉冲激光沉积制备的柱状 BiFeO3 厚膜的表征

利用磁场辅助脉冲激光沉积法在铂/二氧化钛/二氧化硅/硅基底上制备了多晶BiFeO3厚膜。在磁场的限制下，磁流斜入，沉积率高，因此成功获得了厚度为 1.8 μm 的柱状 BiFeO3 厚膜。在柱状 BiFeO3 厚膜中，RT 时获得了饱和 P-E 磁滞环，剩电位极化（Pr）和矫顽力场（Ec）分别为 42 μC cm-2 和 380 kV cm-1。此外，用原子力显微镜测量的压电响应呈蝶形曲线，压电 d33 系数约为 50 pm V-1。
