Piezoelectric nonlinearity and frequency dispersion of the direct piezoelectric response of BiFeO3 ceramics
Tadej Rojac, Andreja Bencan, Goran Drazic +2
We report on the frequency and stress dependence of the direct piezoelectric d33 coefficient in BiFeO3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.…

Surface phase transitions in BiFeO3 below room temperature
R. Jarrier, X. Marti, J. Herrero-Albillos +15
We combine a wide variety of experimental techniques to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature. Raman spectroscopy,…
