Dimensionality-induced change in topological order in multiferroic oxide superlattices

Megan E. Holtz, Elliot S. Padgett, Rachel Steinhardt +5

We construct ferroelectric (LuFeO3)m/(LuFe2O4) superlattices with varying index m to study the effect of confinement on topological defects. We observe a thickness-dependent transi…
