We review the fundamental aspects and applications of functional magneto-optic and opto-
magnetic metamaterials displaying collective and coupling effects on the nanoscale, where …

Natural materials exhibit negligible magnetism at optical frequencies, since the direct effects
of the optical magnetic field on matter are much weaker than electric ones. In the last …

Recent advances in plasmonic-based metamaterials show that the magnetic component of
an optical field can be strongly affected by the material's properties and geometry of metallic …

The weakness of magnetic effects at optical frequencies is directly related to the lack of
symmetry between electric and magnetic charges. Natural materials cease to exhibit …

Due to the lack of symmetry between electric and magnetic charges, the magnetic effect in
optical materials is usually very weak. Recently, Fano type magnetic resonances have been …

The smallness of natural molecules and atoms with respect to the wavelength of light
imposes severe limits on the nature of their optical response. For example, the well-known …

We explore the optical properties of a meta-atom made of plasmonic nanopatches that
possess an increasing degree of complexity. We show that if two nanopatches are strongly …

Magnetoplasmonic crystals are spatially periodic nanostructured magnetic surfaces
combining the features of surface plasmon polariton excitation and magneto-optical …

Hierarchical self-assembled meta-atoms are made from a larger number of suitably
arranged metallic nanoparticles. They constitute the basic building blocks for isotropic …

Magnetoplasmonics is an emerging research area, which is attracting growing interest from
the scientific community. It is part of the more general field of active plasmonics, as it aims at …
