(a) XRD patterns of the ceramics and (b) HRTEM image of the ceramics with the incident beam parallel to the  directions at room temperature, the inset is the elected area electrodiffraction patterns of the sample which was carried out with the incident beams parallel to the  directions
(a) The curves of for both ZFC and FC sequences under the magnetic field , 5 kOe, respectively. The inset indicates the curves under with the -range of 2–100 K. (b) Magnetic hysteresis loop at 2 K in the -range of −20–20 kOe.
-dependence of the dielectric constant and loss over a range of , with a series of measuring frequencies , 30, and 300 kHz, respectively. The inset shows the -dependence of at which the dielectric constant is a maximum.
(a) -dependence of pyroelectric current in the -range of 10–100 K. (b) -dependence of under a series of warming speeds (2, 4, and 6 K/min) in the -range of 10–100 K. (c) -dependence of in the -range of 10–100 K with an electric field (5 kV/cm) applied along the thickness direction. The inset indicates in the -range of 10–40 K. (d) -dependence of under a positive or negative poling electric field (±5 kV/cm), over a range of .
XRD patterns of ceramics measured at 300, 90, 30 and 10 K, respectively. The inset shows the locally amplified XRD patterns of ceramics.
