We consider the optical plug at the center of the vortex, which makes the vortex-creation process stable. We also investigate the instability of the halfway state to complete vortex state without the optical plug.6 pages, 5 figures, manuscript for QFS2001Soft Condensed MatterStability of a Vortex in Spinor Bose-Einstein Condensatetext
