Extended Data Fig. 4: Magnetic domain wall in the easy-axis ferromagnetic phase.
From: Universality class of a spinor Bose–Einstein condensate far from equilibrium
a, Magnetization Fz after 1.5 s of hold time, and b, the cross-section profile across the magnetic domain. The solid line is a fit curve \({F}_{z}(r)={F}_{z0}\tanh (r/{\xi }_{d})\) with ξd = 4.5(2) μm. c,d, Magnetization along the horizontal axis Fx. The spin vectors could be aligned on the same axis (c, Bloch or Neel-type domain wall) or point in opposite directions (d, Bloch line). A long wavelength modulation of the horizontal spin vector could imply the presence of spin wave excitations in the magnetic domain.
