• The spinor Bose-Einstein condensate of atomic gases has been experimentally realized by a number of groups. Further, theoretical proposals of the possible vortex states have been suggested. This paper studies the effects of the quadratic Zeernan energy on the vortex states. This energy was ignored in previous theoretical studies, although it exists in experimental systems. We present phase diagrams of various vortex states by considering the quadratic Zeeman energy. The vortex states are calculated by the Gross-Pitaevskii equation. Several new types of vortex states are found. Further, it is found that the quadratic Zeeman energy affects the direction of total magnetization and results in a significant change in the phase diagrams.
