TL;DR
This paper investigates how hot electrons can enhance spin-lattice coupling in 4f ferromagnets, using femtosecond x-ray magnetic circular dichroism to observe the effects.
Contribution
It introduces a novel experimental approach to directly observe hot electron effects on spin-lattice interactions in 4f ferromagnets.
Findings
Hot electrons significantly enhance spin-lattice coupling.
Femtosecond x-ray magnetic circular dichroism effectively captures ultrafast magnetic dynamics.
The study provides insights into controlling magnetic properties via hot electron excitation.
