Characterization of Multiferroic Domain Structures in Multiferroic Oxides

Figure 3

(a) A conventional dark-field TEM image of the multiferroic cloverleaf domains in the YMnO₃ crystal near the zone axis [21]. Note that the domains are elongated along the c-axis as indicated with an arrow. (b) An enlargement of the vortex designated by a white rectangle is shown as a pseudocolor representation. (c) An instable vortex observed in some field of view.
