Angular momentum of light and all-optical magnetization reversal
Our study examines how light's angular momentum affects magnetic all-optical switching (AOS), which involves reversing magnetization using ultrafast laser pulses on a magnetic structure. The magnetic system consists of a ferromagnetic thin sheet of Co/Pt, which is stimulated by Femtosecond vortex beams of light can carry spin, orbital angular momentum, or both.
