  Coreless vortices were phase-imprinted in a spinor Bose-Einstein condensate.
The three-component order parameter of F=1 sodium condensates held in a
Ioffe-Pritchard magnetic trap was manipulated by adiabatically reducing the
magnetic bias field along the trap axis to zero. This distributed the
condensate population across its three spin states and created a spin texture.
Each spin state acquired a different phase winding which caused the spin
components to separate radially.
