  Long-range spin transport in magnetic systems can be achieved by means of
exchange-mediated spin textures with robust topological winding -- a phenomenon
referred to as spin superfluidity. Its experimental signatures have been
discussed in antiferromagnets which are nearly free of dipolar interaction.
However, in ferromagnets, which possess non-negligible dipole fields,
realization of such spin transport has remained a challenge. Using
micromagnetic simulations, we investigate coherent exchange-mediated spin
transport in extended thin ferromagnetic films. We uncover a two-fluid state,
in which the long-range spin transport by spin textures co-exists with spin
waves, as well as a soliton-screened spin transport regime at high spin
injection biases. Both states are associated with distinct spin texture
reconstructions near the spin injection region and sustain spin transport over
large distances.
