Abstract
The persistent spin current in an anisotropic spin ring penetrated by a SU(2) flux is studied by the Schwinger-Boson mean-field approach. The anisotropy in spin coupling can facilitate the persistent spin current. Ground-state energy and excitation-energy gap are also studied. A peak of spin current occurs at the maximum value of the ground-state energy.
