Phase-Space Quantum Geometry Beyond Adiabatic Electron Dynamics
Luca Maranzana, Koki Shinada, Ying-Ming Xie +2
The geometry of electronic quantum states plays an important role in the equilibrium and transport properties of solids. While the Berry curvature is known to influence electron mo…
Highly controllable switching pathways in multiferroic GdMnO
M. Ryzhkov, A. Granero, J. Wettstein +7
Controlling magnetic moments using electric fields remains a central challenge in spintronics. Multiferroics, where magnetic and electric orders coexist, may be a natural platform…
Rocket-like dynamics of ferrimagnetic domain walls in graded materials
P. Diona, S. Artyukhin, L. Maranzana
Domain wall motion underpins emerging spintronic technologies, such as high-speed racetrack devices and THz logic, and accelerating walls quickly is a key challenge on the path to…
Thermal conductivity in noncollinear magnets
Margherita Parodi, Sergey Artyukhin
Magnetic memory and logic devices, including prospective ones based on skyrmions, inevitably produce heat. Thus, controlling heat flow is essential for their performance. Here we s…
Finite temperature magnetic interactions from first principles
Ravi Kaushik, Ryota Ono, Sergey Artyukhin
Density functional theory has demonstrated remarkable predictive power in calculating magnetic properties at zero temperature. At finite temperatures, thermally excited phonons may…
Observation of relativistic domain wall motion in amorphous ferrimagnets
Pietro Diona, Luca Maranzana, Sergey Artyukhin +1
Domain walls in ferrimagnets and antiferromagnets behave as relativistic sine-Gordon solitons with the spin-wave group velocity setting the ultimate velocity of domain walls and sp…
Competition Between Multiferroic and Magnetic Soliton Lattice States in DyFeO
S. E. Nikitin, N. D. Andriushin, Ø. S. Fjellvåg +5
Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be use…
Topological pumping of bimerons in spiral magnets
Luca Maranzana, Maxim Mostovoy, Naoto Nagaosa +1
Precise positioning of topological defects is essential for racetrack memories, where their positions along a magnetic nanotrack encode information. Traditional methods achieve nan…
Entangled orbital, spin, and ferroelectric orders in -electron magnet CsO
Ryota Ono, Ravi Kaushik, Sergey Artyukhin +3
Alkali superoxides differ from conventional transition metal magnets, exhibit magnetism from partially occupied oxygen molecular -orbitals. Among them, CsO stands out for…
Interplay of trimerization, chirality and ferroelecticity in multiferroic BaCoSiO4
Aditya Putatunda, Sergey Artyukhin
Multiferroic materials combine multiple ferroic orders that may enable cross-functionalities, e.g. control of one ferroic order by the field conjugate to the other one. BaCoSiO…
Merons, hedgehogs and magnetoelectric switching in spiral multiferroics
Luca Maranzana, Naoto Nagaosa, Sergey Artyukhin
In spiral multiferroics, magnetism induces ferroelectricity, thus holding a promise for novel memory devices where an electric field switches magnetic bits. However, such a switchi…
Electric field-induced domain wall motion in spin spiral multiferroics
Francesco Foggetti, Margherita Parodi, Naoto Nagaosa +1
Switching in magnetic materials gives rise to rich physical phenomena and lies at the heart of their technological applications. Although domain wall motion in ferro- and antiferro…
Spin-Wave Relaxation in a Quantum Hall Ferromagnet
S. Dickmann, S. L. Artyukhin
We study spin wave relaxation in quantum Hall ferromagnet regimes. Spin-orbit coupling is considered as a factor determining spin nonconservation, and external random potential as…
