Optically Induced Interaction of Magnetic Moments in Hybrid Metamaterials

We propose a novel type of hybrid metal dielectric structures composed of silicon nanoparticles and split-ring resonators for advanced control of optically induced magnetic response. We reveal that a hybrid metamolecule may exhibit a strong distance-dependent magnetic interaction that may flip the magnetization orientation and support antiferromagnetic ordering in a hybrid metamaterial created by a periodic lattice of such metamolecules. The propagation of magnetization waves in the hybrid structures opens new ways for manipulating artificial antiferromagnetic ordering at high frequencies.
