Understanding depoling behavior through property and structure measurements of Fe-doped NBT Piezoelectric constant measured as a function of temperature both in situ (a) and ex situ (b). X-ray diffraction patterns measured as a function of temperature for undoped (a) and 1% Fe-doped (b) NBT. Permittivity and loss measured as a function of temperature measured for poled and unpoled samples.
