Query: Internal Vortex Structure of a Trapped Spinor Bose-Einstein Condensate   The internal vortex structure of a trapped spin-1 Bose-Einstein condensate is
investigated. It is shown that it has a variety of configurations depending on,
in particular, the ratio of the relevant scattering lengths and the total
magnetization.
