Abstract: The recent experimental creation of Shankar skyrmion in ferromagnetic spin-1 Bose–Einstein condensates opens an interesting pilot for exploring the stability and dynamics of the three-dimensional skyrmion. We find similar vortex rings can be accommodated in the spin-orbit coupled ferromagnetic spin-1 Bose–Einstein condensates. However, the composite vortex rings has mixing manifolds of ferromagnetic and antiferromagnetic states, where the Shankar skyrmion is hidden. Our results suggest an alternative way of creating skyrmion-like vortex rings in spin-1 Bose–Einstein condensates.
