We construct ferroelectric (LuFeO3)m/(LuFe2O4) superlattices with varying index m to study the effect of confinement on topological defects. observe a thickness-dependent transition from neutral charged domain walls and emergence fractional vortices. In thin LuFeO3 layers, volume fraction grows, lowering symmetry P63cm P3c1 before reaching non-polar P63/mmc state, analogous high-temperature par...
