Unravelling the role of Sm 4f electrons in the magnetism of SmFeO
Danila Amoroso, Bertrand Dupe, Matthieu J. Verstraete
Magnetic rare-earth orthoferrites FeO host a variety of functional properties from multiferroicity and strong magnetostriction, to spin-reorientation transitions and ultrafa…
Spin-current driven Dzyaloshinskii-Moriya interaction in the multiferroic BiFeO3 from first-principles
Sebastian Meyer, Bin Xu, Matthieu Verstraete +2
The electrical control of magnons opens up new ways to transport and process information for logic devices. In magnetoelectrical multiferroics, the Dzyaloshinskii-Moriya (DM) inter…
Polar meron-antimeron networks in strained and twisted bilayers
Daniel Bennett, Gaurav Chaudhary, Robert-Jan Slager +2
Out-of-plane polar domain structures have recently been discovered in strained and twisted bilayers of inversion symmetry broken systems such as hexagonal boron nitride. Here we sh…
The impact of valley profile on the mobility and Kerr rotation of transition metal dichalcogenides
Thibault Sohier, Pedro M. M. C. de Melo, Zeila Zanolli +1
The transport and optical properties of semiconducting transition metal dichalcogenides around room temperature are dictated by electron-phonon scattering mechanisms within a compl…
Coupling between tilts and charge carriers at polar-nonpolar perovskite interfaces
Daniel Bennett, Pablo Aguado-Puente, Emilio Artacho +1
The phenomenological theory for the polar instability giving rise to a two-dimensional electron gas at perovskite interfaces is hereby extended to include the coupling to perovskit…
Generalized relation between electromechanical responses at fixed voltage and fixed electric field
Daniel Bennett, Daniel Tanner, Philippe Ghosez +2
We present a general relation between the electromechanical couplings of infinitesimal strain and electric field to arbitrary order, measured at fixed voltage and at fixed electric…
