A net circulating current may appear within a quantum ring under finite bias.We study the characteristic features of the circular current in the presence ofRashba spin-orbit interaction (RSOI). Both charge and spin currents appearwithin the ring. Whereas when the ring is symmetrically connected to theexternal leads, we can get a pure charge current at non-zero Fermi-energy. Onthe other hand, for asymmetric ring-to-leads configuration, at zeroFermi-energy, the spin current vanishes but a pure charge current flows withinthe ring. Tuning RSOI, we demonstrate a way to control the pure spin currentexternally. This new perspective of the generation of the pure spin circularcurrent can open a new basis for the highly efficient, low energy costspintronic devices.
