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…
