From: Long-range Stripe Nanodomains in Epitaxial (110) BiFeO3 Thin Films on (100) NdGaO3 Substrate
PFM images of BFO films showing out-of-plane (OP) and In-plane (IP) phase and amplitude contrast corresponding to BFO/NGO (a–d) and BFO/LSCO/NGO (e–h) heterostructures with stripe nanodomains in the areas of Fig. 2a,b, respectively. (i) Schematics of the polarization variants in (100) and (110) BFO films with the possible combinations of bidomain variants corresponding to 71°, 109°, and 180° domain wall orientations. The arrows represent the spontaneous polarization directions. (j) Schematic illustration of the 109° domain structure in BFO/NGO heterostructure.
