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…
Nucleation instability preempts relativistic domain wall transport in high-exchange ferrimagnetic nanowires
Pietro Diona
Current-driven domain wall motion in ferrimagnets can approach the spin-wave velocity, giving rise to relativistic-like dynamics. While this regime has been experimentally observed…
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…
