From: Propelling ferrimagnetic domain walls by dynamical frustration

Fig. 3

Worldlines end either when a left-moving and a right-moving domain collide or when the distance between two domain walls shrinks to zero. Colour: amplitude of ∂xφ in units of δφ, given by the difference of phase gradients δφ = ∂xφleft − ∂xφright ≈ 0.176 across a single domain wall, see Fig. 1b, c. The motion of domain walls is subject to a long-range hydrodynamic interaction mediated by ∂xφ. Parameters: same as in Fig. 1, initial state: ordered xy-AFM with a small random \({S}_{i}^{z}=\pm 0.1\), see section “Methods”.
