Abstract
We show that the Landau vortex-free state in rotating container may give rise to
the lattice of spin vortices. We consider this effect on example of spin
vortices in magnon Bose-Einstein condensate (the phase coherent spin precession)
in the B-phase of superfluid 3He, and on example of spin vortices in the
polar phase of 3He.
