  Magnetic domain patterns in a ferromagnetic Bose-Einstein condensate (BEC)
show different properties depending on the quadratic Zeeman effect and
dissipation. Another important factor that affects domain patterns and domain
growth is superfluid flow of atoms. Domain growth in a ferromagnetic BEC with
negative quadratic Zeeman energy is characterized by the same growth law as
(classical) binary fluid in the inertial hydrodynamic regime. In the absence of
the superfluid flow, the domain growth law for negative quadratic Zeeman energy
is the same as that of scalar conserved fields such as binary alloys.
