With the aim of observing magnetization induced by the inverse Faraday effect of surface plasmon polariton spin skyrmions using magneto-optical Kerr effect microscopy, electromagnetic field analysis was performed using the finite-difference time-domain method. The results demonstrated that the magnitude of the spin and the topological structure can be controlled by the radius of the coupler.
