Crossover from Universal Depinning to Free Domain-Wall Dynamics in Ultrathin Iron Garnet Films
V. Jeudy, D. Gouéré, N. Beaulieu +7
Magnetic domain walls display universal, disorder-controlled elastic dynamics at low drive, and texture-governed free motion at high drive. Here, we establish the crossover mechani…
