Kurzbeschreibung (Abstract)
The field-induced jump-like dynamics of a single planar domain wall are investigated in single crystal uniaxial ferroelectric–ferroelastic Gd2(MoO4)3 containing extended bulk defects. The kind and location of the defects interfering with the free motion of the domain wall determines which type of elastic vibration is excited by the discontinuous jump of the domain wall. Time coincidence between optically observed jumps, Barkhausen pulses, and acoustic emissions each occur for particular jumps only. The time coincidence conditions correlate with the vibration spectra and differ for the initial release of the wall, large domain wall jumps, and clamped motions.
