摘要：
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.
