  The existing proposals for superfluid-like spin transport have been based on
easy-plane magnets where the U(1) spin-rotational symmetry is spontaneously
broken in equilibrium, and this has been limiting material choices for
realizing superfluid-like spin transport to restricted class of magnets. In
this work, we lift this limitation by showing that superfluid-like spin
transport can also be realized based on easy-axis magnets, where the U(1)
spin-rotational symmetry is intact in equilibrium but can be broken in
non-equilibrium. Specifically, we find the condition to engender a
non-equilibrium easy-cone state by applying a spin torque to easy-axis magnets,
which dynamically induces the spontaneous breaking of the U(1) spin-rotational
symmetry and thereby can support superfluid-like spin transport. By exploiting
this dynamic easy-cone state, we show theoretically that superfluid-like spin
transport can be achieved in easy-axis magnets under suitable conditions and
confirmed the prediction by micromagnetic simulations. We envision that our
work broadens material library for realizing superfluid-like spin transport,
showing the potential utility of dynamic states of magnets as venue to look for
spin-transport phenomena that do not occur in static magnetic backgrounds.
