arising from: Y. Liu et al. Nature Materials https://doi.org/10.1038/s41563-018-0152-z (2018)

In their recent Article, Liu et al.1 conclude that “Our results clarify that previous claims on ferroelectricity are, in fact, misguided by the elastic variation between the domains, rather than by true piezoelectric (electromechanical) effects, which suggests the twin domains are non-ferroelectric”. However, their underlying interpretation of the band excitation frequency tracking results is flawed, and their presented data can well be explained by ferroelectric sample polarization.
