 Magnetization reversal by circularly polarized light

Magnetization reversal by circularly polarized light refers to the process of changing the magnetization direction of a material by exposing it to circularly polarized light, which consists of electromagnetic waves that have a specific helicity or rotational direction. This technique is particularly significant in the field of spintronics and magnetic data storage, as it offers a potentially fast and energy-efficient means to manipulate magnetic states.
