Abstract
Bose-Einstein condensation in alkali atoms has materialized quite an intere sting system, namely a condensate with a spin degree of freedom. In analogy with the A-phase of the superfluid He-3, numerous textures with nonvanishi ng vorticity have been proposed. In the present paper, interesting properti es of such spin textures are analyzed. We propose a remarkably simple metho d to create a vortex state of a BEC in alkali atoms.
