XRD patterns of BFO films grown on STO (001) and SRO buffered STO (001) at 600 °C. The BFO/SRO thicknesses are 13/0 nm and 17/27 nm, respectively. The inset shows the rocking curve for the (002) peak of the SRO buffered BFO film.
(Color online) (a) Reciprocal space mappings around the (103) reflections, and phi scan of the (b) BFO and (c) STO (101) reflections of the SRO buffered BFO film.
Temperature dependent and field dependent (inset) magnetization of BFO films grown on (a) STO (001) and (b) SRO buffered STO (001). The diamagnetic signals from the STO substrates are not subtracted except in inset (b).
(Color online) (a) AFM topography, (b) OP, and (c) IP PFM images of the SRO buffered BFO film. Please note (b) and (c) share the same color bar on the right.
(Color online) (a) Domain switching process after polling at different bias voltages, and local switching spectroscopy PFM (b) amplitude and (c) phase curves of the SRO buffered BFO film.
