Figure 2: Electric-field-driven injection and positioning of a domain wall.
From: Polarization control at spin-driven ferroelectric domain walls
(a) Schematic illustration of the setup and sample orientation in between two metallic electrode plates. (b) SHG image of a ferroelectric single-domain state (−Pb) taken after electric field poling. (c–f) Image sequence documenting the injection and subsequent positioning of a ferroelectric domain wall at a constant electric field −Eb=4.8 kV cm−1. Note the general preference for side-by-side domain walls with only the transient occurrence of short head-to-head or tail-to-tail sections in the course of wall progression. All images were taken at 9 K at a SHG photon energy of 2.1 eV. Scale bar, 250 μm.
