Abstract
Recently new topological phase of superfluid 3He has been discovered -
the β phase, which is obtained by strong polarization of the
nematic polar phase. We consider half-quantum vortices, which are formed
in rotating cryostat, and discuss the evolution of the vortex lattice in
the process of the transition from the polar phase to the β-phase
via the spin-polarized polar phase.
