X-ray diffraction patterns of BFO films with various thicknesses. The inset shows thickness-dependent full width at half maximum of (012) peak.
Images of AFM surface morphology (left) and corresponding piezoresponse (right) of the BFO films with thickness of about (a) 35 and (b) 120 nm. The piezoresponse (c) phase and (d) amplitude loops for the 120 nm BFO films.
In-plane magnetic hysteresis loops of BFO films with various thicknesses. Inset I plots the thickness-dependent saturation magnetization and the magnetization of unit area . Inset II shows the calculated result of thickness-dependent .
The in-plane and out-of-plane magnetization-field curves for the BFO films with thickness of about (a) 35, (b) 60, and (c) 120 nm. (d) shows thickness-dependent magnetic anisotropy field . The inset in (d) shows thickness-dependent and .
