  We analyze a metal-dielectric structure composed of a silicon nanoparticle
coupled to a stack of split-ring resonators, and reveal the possibility of
optically-induced antiferromagnetic response of such a hybrid meta-molecule
with a staggered pattern of the induced magnetization. We show that a hybrid
metamaterial created by a periodic lattice of the meta-molecules supports
antiferromagnetic modes with a checker-board pattern and the propagation of
spin waves, opening new ways for manipulating artificial antiferromagnetism at
high frequencies with low-loss materials.
