The inverse Faraday effect is a magneto‐optical process allowing the magnetization of matter by an optical excitation carrying non‐zero spin. In particular, right circular polarization generates in direction light propagation and left opposite to this propagation. Herein, it demonstrates that manipulating spin density light, i.e., its polarization, plasmonic nanostructure, reversed generated. A will generate propagation, Also, new physical phenomenon chiral, generating strong magnetic field only for one helicity producing mirror structure. This concept opens way generation fields with unpolarized finding application ultrafast manipulation domains processes, such as precession, currents, waves, skyrmion or dichroism, direct applications data storage processing technologies.
