Deterministic control of antiferromagnetic domain walls by circular phonons
Vladislav Bilyk, Nikolai Khokhlov, Viktoriia Radovskaia +12
In an antiferromagnet, areas with different orientations of the antiferromagnetic Néel vector, which plays the role of the order parameter, can coexist, thus forming antiferromagne…
Exchange striction determines how fast antiferromagnetic insulators demagnetize
Aleksandr Buzdakov, Ravi Kaushik, Nikolai Khokhlov +2
Antiferromagnets combine terahertz spin dynamics with insensitivity to stray fields, and how quickly their order can be manipulated sets the speed limit on device operation. Femtos…
Phase Transitions in Low-Dimensional Layered Double Perovskites: The Role of the Organic Moieties
Beatriz Martín-García, Davide Spirito, Giulia Biffi +3
Halide double perovskites are an interesting alternative to Pb-containing counterparts as active materials in optoelectronic devices. Low-dimensional double perovskites are fabrica…
Multiferroic kinks and spin-flop transition in NiInSbO from first principles
Ryota Ono, Igor Solovyev, Sergey Artyukhin
Magnetoelectric multiferroics are key materials for next-generation spintronic devices due to their entangled magnetic and ferroelectric properties. Spiral multiferroics possess fe…
Microscopic Origin of the Electric Dzyaloshinskii-Moriya Interaction
Peng Chen, Hong Jian Zhao, Sergey Prosandeev +2
The microscopic origin of the electric Dzyaloshinskii-Moriya interaction (eDMI) is unveiled and discussed by analytical analysis and first-principles based calculations. As similar…
Ferroelectricity and topological vortices from molecular ordering in metal-organic frameworks
Francesco Foggetti, Alessandro Stroppa, Sergey Artyukhin
Metal-organic frameworks comprehend a wide class of hybrid organic-inorganic materials with general structure ABX, with and being organic molecules and B a metal ca…
Liberation of slave modes inside domain walls in multiferroic Cu-Cl boracite
Peng Chen, Sergey Artyukhin
Domain walls (DWs), the two-dimensional boundaries between symmetry equivalent ferroic domains, are actively investigated due to their promise for novel logic and memory devices. M…
Unexpected Giant Microwave Conductivity in a Nominally Silent BiFeO3 Domain Wall
Yen-Lin Huang, Lu Zheng, Peng Chen +10
Nanoelectronic devices based on ferroelectric domain walls (DWs), such as memories, transistors, and rectifiers, have been demonstrated in recent years. Practical high-speed electr…
Activation of nominally silent domain wall-localized phonons from GHz to THz frequencies
Peng Chen, Louis Ponet, Keji Lai +2
Ferroelectric domain walls (DWs) are nanoscale topological defects that can be easily tailored to create nanoscale devices. Their excitations, recently discovered to be responsible…
First-principles theory of giant Rashba-like spin-splitting in bulk ferroelectrics
Louis Ponet, Sergey Artyukhin
Recently large Rashba-like spin splitting has been observed in certain bulk ferroelectrics. In contrast with the relativistic Rashba effect, the chiral spin texture and large spin-…
Successive magnetic field-induced transitions and colossal magnetoelectric effect in NiTeO
Jae Wook Kim, S. Artyukhin, E. D. Mun +8
We report the discovery of a metamagnetic phase transition in a polar antiferromagnet NiTeO that occurs at 52 T. The new phase transition accompanies a colossal magnetoelec…
Magneto-absorption spectra of hydrogen-like yellow exciton series in cuprous oxide: excitons in strong magnetic fields
Sergey L. Artyukhin, Dmitry Fishman, Clément Faugeras +4
We study the absorption spectra of the yellow excitons in CuO in high magnetic fields using polarization-resolved optical absorption measurements with a high frequency resoluti…
