The role of spin-lattice interaction in optical control of magnetism — •Alexey Kimel — Radboud University, Nijmegen, The Netherlands

The action of electric field of light on electronic dipoles, being the largest perturbation in physics of light-matter interaction, conserves the spin of electron. This is why experiments showing the possibility of ultrafast and efficient control of spins with the help of femtosecond laser pulses are among the most heavily debated topics in magnetism. In my talk I will review the progress in understanding of ultrafast laser-induced magnetization dynamics. In particular, I would like to discuss the roles of the spin-lattice interaction in heat-driven, heat-assisted, and heat-free mechanisms of optical control of magnetic order.
