Ferroelectric Domains in ErMnO3

Topological ramification: Piezoresponse force microscopy image of the ferroelectric domain structure of hexagonal ErMnO3. Dark and bright areas correspond to opposite out-of-plane directions of the polarization. Each branch originates at a vortex-like intersection of six individual domains being topologically enforced to reunite at the anti-vortex counterpart inside or outside of the image. The image has been recorded at room temperature. 


Ferroelectric Domains in DyMnO3

DyMnO3, z-cut, single crystal Ferroelectric Domains in DyrMnO3 Bright and dark areas correspond to positively and negatively polariszed domains. The meeting point of always 3 bright and 3 dark domains are topological defects and named ferroelectric vortices.


Ferroelectric Domains in YrMnO3

YMnO3, z-cut, single crystal Ferroelectric Domains in YrMnO3 Bright and dark areas correspond to positively and negatively polariszed domains. The meeting point of always 3 bright and 3 dark domains are topological defects and named ferroelectric vortices.


Ferroelectric Domains in ErMnO3

ErMnO3, z-cut, single crystal Ferroelectric Domains in ErMnO3 Bright and dark areas correspond to positively and negatively polariszed domains. The favor of the negatively polarzied domains is due to oxygen loss of the surface during the growth. The meeting point of always 3 bright and 3 dark domains are topological defects and named ferroelectric vortices.


Domains walls of ferroelectric domains in RbHSO4

RbHSO4 single crystal, z.cut Domains walls of ferroelectric domains in RbHSO4 measured at -30°C with the help of an home build cooling stage. Bright and dark areas correspond to a forward or backward sheer motion of the crystal. Polarrization is oriented ou-of-plane with the bubbles beeing positively polarized.
