abstract = {Ferroelectric materials find application in numerous
electronic devices and are continuously enabling the
development of new technologies. Their versatility is
intimately related to the unique property to switch the
polarization with electric fields. However, the switching
mechanisms in polycrystalline ferroelectric materials remain
insufficiently understood. Here we reveal that switching in
ferroelectric/ferroelastic materials consists of a sequence
of individual events, separated into three regimes: rapid
movement of non-180° domain walls, main switching phase
with 180° and non-180° switching events, and creep-like
non-180° domain wall movement. The determination of the
mechanisms was enabled by a novel measurement approach,
simultaneously tracking the time dynamics of switched
polarization, macroscopic strain, and structural changes.
Time-resolved in situ synchrotron diffraction allowed direct
insight into the non-180° domain wall dynamics and lattice
strains and gave evidence for strong time correlation of
non-180° switching events in different grains of the
polycrystalline material. The obtained results open new
opportunities for targeted manipulation of individual
switching events and tuning of material's functional
properties.},
