"Laser-driven spin dynamics in ferrimagnets: How does the angular momentum flow?." ScienceDaily. www.sciencedaily.com / releases / 2019 / 05 / 190502100831.htm (accessed December 1, 2025).
When exposed to intense laser pulses, the magnetization of a material can be manipulated very fast. Fundamentally, magnetization is connected to the angular momentum of the electrons in the material.
