我们提出了一种新型的混合金属介电结构组成的硅纳米粒子和开口环谐振器的光致磁响应的先进控制。我们发现，混合“超分子”可能表现出强烈的距离依赖性的磁相互作用，可以翻转的磁化方向和支持“反铁磁”有序的混合超材料中创建的周期性晶格这样的超分子。磁化波在混合结构中的传播为在高频下操纵人工“反铁磁”有序化开辟了新的途径。
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.
