Understanding the local structure, magnetism and optical properties in layered compounds with d9 ions: Insight into silver fluorides and K2CuF4
Inés Sánchez-Movellán, Guillermo Santamaría-Fernández, Pablo García-Fernández +2
Using first-principles DFT calculations, we analyze the origin of the different crystal structures, optical and magnetic properties of two basic families of layered fluoride materi…
Kittel law and domain formation mechanism in PbTiO/SrTiO superlattices
Fernando Gómez-Ortiz, Hugo Aramberri, Juan M. López +3
We report second-principles simulations on the structural and energetic properties of domains in (PbTiO)/(SrTiO) superlattices. For the explored layer thick…
Berezinskii-Kosterlitz-Thouless phases in ultra-thin PbTiO/SrTiO superlattices
Fernando Gómez-Ortiz, Pablo García-Fernández, Juan M. López +1
We study the emergence of Berezinskii-Kosterlitz-Thouless (BKT) phases in (PbTiO)/(SrTiO) superlattices by means of second-principles simulations. Beyond a threshol…
Melting of Polarization Vortices Crystals and Chiral Phase Transitions in Oxide Superlattices
Fernando Gómez-Ortiz, Pablo García-Fernández, Juan M. López +1
We study the equilibrium arrangements of polarization vortices in (PbTiO)/(SrTiO) superlattices by means of second-principles simulations. We find that, at low temp…
