Magnetic dipole moment generated in nano-droplets irradiated by circularly polarized laser pulse

Abstract

A new mechanism to generate nanometer-scale magnetic dipoles is presented with the help of particle-in-cell simulations and analytical modeling. The kilo-tesla axial magnetic field is sustained by electrons orbiting around spherical clusters after the interaction with a circularly polarized laser pulse. The magnetization of material in such way is different from the inverse Faraday rotation and the localized magnetic fields have a much higher amplitude.
