Previous studies on ferromagnetic ring structures have shown that the asymmetry induced by the decenter of inner core contributes to the global vortex state. In this work, the asymmetric Co rings with decentered elliptic inner core are investigated with simulation. The coexistence of the asymmetry originated from the decentered direction and distance of the core, and the one from the elliptic direction and shape ratio, makes the magnetization reversal more complex. The simulation shows that the magnetization reversal processes in asymmetric Co rings with elliptic inner core aligned along either X or Y axis are similar to each other. This indicates that the asymmetry introduced by the elliptic inner core is not as significant as that introduced by the decenter of the core. The effects of shape ratio and decentered distance of the core show that compared to the narrow elliptic slit, a round core and a large decentered distance are beneficial to the achievement of global vortex state at remanence.
