X-ray diffraction patterns of undoped and -doped ranging from Fe.
Polarization and strain hysteresis for undoped (open symbols) and -doped (bold symbols) ceramics (see Ref. 20).
X-band (9.8 GHz) EPR-spectra of -doped for varying dopant concentrations (bold) as compared to (dashed) at ambient temperature. (a) -doped BNT powders calcined at for 2 h. (b) -doped BNT ceramics sintered at for 1 h. The vertical dashed line represents and the vertical dotted line marks the effective -value for the observed secondary phase.
Schematic illustration of the defect-structural arrangement of the (truncated) oxygen octahedra for undoped (a) and -doped BNT containing a defect dipole (b). The corresponding orientations of spontaneous polarization and defect polarization are indicated by arrows.
