Annealing of skyrmion lattice in van der Waals magnet via field modulation (opens in new tab)

In atomic solids, annealing transforms disordered structures into ordered crystals through thermal activation, whereas realizing a comparable process in quasiparticle lattices is highly desirable. Magnetic skyrmions are topological spin textures that can form ordered lattice and undergo equilibrium phase transitions, yet thermal activation is insufficient to overcome their kinetic constraints or provide tunable control. Here, we demonstrate field-driven annealing of skyrmions in two-dimension...
