Magnetic moment generation in small gold nanoparticles via the plasmonic inverse Faraday effect

Inverse Faraday effect in plasmonic heterostructures

The phenomenon of the surface plasmon assisted electromagnetic field concentration in the vicinity of the metal/dielectric interface of a periodically perforated with subwavelength holes arrays plasmonic structure is considered. An increase of the local stationary magnetic field appearing due to the inverse Faraday effect while the heterostructure is illuminated by circularly polarized light is...

Magnetization dynamics in dysprosium orthoferrites via the inverse Faraday effect

The ultrafast nonthermal control of magnetization has recently become feasible in canted antiferromagnets through photomagnetic instantaneous pulses A. V. Kimel et al., Nature 435, 655 2005 . In this experiment, circularly polarized femtosecond laser pulses set up a strong magnetic field along the wave vector of the radiation through the inverse Faraday effect, thereby exciting nonthermally the...

Faraday effect in hybrid magneto-plasmonic photonic crystals.

We present a theoretical study of the Faraday effect in hybrid magneto-plasmonic crystals that consist of Au-Co-Au perforated membranes with a periodic array of sub-wavelength holes. We show that in these hybrid systems the interplay between the extraordinary optical transmission and the magneto-optical activity leads to a resonant enhancement of the Faraday rotation, as compared to purely ferr...

Thermoinduced magnetic moment in akaganéite nanoparticles

Theoretical investigation of the inverse Faraday effect via a stimulated Raman scattering process

We study theoretically the origin and mechanism of the ultrafast inverse Faraday effect, which is a magnetooptical effect, attracting much interest nowadays. Laser-induced subpicosecond spin dynamics in hydrogenlike systems and isolated many-electron atoms are investigated in order to get insight into this process. We show that the stimulated Raman scattering process leads to a change of the ma...
