Effect of the local field and dipole-dipole interaction on the spontaneous ordering of dipole moments in bismuth monolayers with an orthorhombic structure

D. V. Ponkratova, I. V. Zagorodnev, V. V. Enaldiev

The paper studies how local Lorentz‑Lorenz fields and dipole‑dipole interactions can induce spontaneous electric dipole moments, leading to ferroelectric and antiferroelectric orde…
