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…
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…
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…
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…
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…
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…
