Quasicrystalline oxide interfaces by twisting SrTiO3 membranes
Shivasheesh Varshney, Sooho Choo, Huan Liu +34
Quasicrystals reveal that long-range order can exist without translational periodicity, but deterministic routes for designing strongly bonded quasicrystalline interfaces remain un…
Designing dislocation-driven polar vortex networks in twisted perovskites
William Sandholt, Nicolas Gauquelin, John Mangeri +21
Twisting two atomic layers produces a geometric moire pattern, but bonding-induced interfacial reconstruction fundamentally transforms this into an ordered dislocation network - a…
Fully characterized linear magnetoelectric response of 2D monolayers from high-throughput first-principles calculations
John Mangeri, Thomas Olsen
We screen 4784 stable monolayers from the Computational 2D Materials Database (C2DB) and identify 57 ferromagnetic (FM) and 67 antiferromagnetic (AFM) compounds that should exhibit…
Magnetoelectric behavior of breathing kagomé monolayers of from first-principles calculations
John Mangeri, Varun R. Pavizhakumari, Thomas Olsen
We apply density functional theory to explore the magnetoelectric (ME) properties of two-dimensional . These compounds have recently been propose…
Extrinsic Dielectric Response due to Domain Wall Motion in Ferroelectric BaTiO
Ashok Gurung, Mohammad Fatin Ishtiyaq, S. Pamir Alpay +2
BaTiO (BTO) is a prototypical perovskite ferroelectric, whose dielectric permittivity and loss spectra -- which are strongly temperature and frequency dependent -- include cont…
Linear magnetoelectricity in the Zintl phase pnictides (Ba, Ca, Sr) from first principles calculations
John Mangeri, Martin Ovesen, Thomas Olsen
We report a comprehensive set of density functional theory calculations on the family of layered antiferromagnetic manganese pnictides (Ba, Ca, Sr)$\mathrm{Mn}_2\mathrm{(P, As, Sb)…
Understanding magnetoelectric switching in BiFeO thin films
Natalya S. Fedorova, Dmitri E. Nikonov, John M. Mangeri +3
In this work we use a phenomenological theory of ferroelectric switching in BiFeO thin films to uncover the mechanism of the two-step process that leads to the reversal of the…
Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
A coupled magneto-structural continuum model for multiferroic
John Mangeri, Davi Rodrigues, Sudipta Biswas +3
A continuum approach to study magnetoelectric multiferroic (BFO) is proposed. Our modeling effort marries the ferroelectric (FE) phase field method and micromagn…
Domain alignment within ferroelectric/dielectric PbTiO/SrTiO superlattice nanostructures
J. Park, J. Mangeri, Q. Zhang +7
The ferroelectric domain pattern within lithographically defined PbTiO3/SrTiO3 ferroelectric/dielectric heteroepitaxial superlattice nanostructures is strongly influenced by the ed…
Controllable skyrmion chirality in ferroelectrics
Yu. Tikhonov, S. Kondovych, J. Mangeri +9
Chirality, an intrinsic handedness, is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging f…
