ScienceTechyNews: Laser-driven spin dynamics in ferrimagnets: How does the angular momentum flow?

A team of researchers led by scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin has now been able to follow the flow of angular momentum during ultrafast optical demagnetization in a ferrimagnetic iron-gadolinium alloy in great detail, in order to understand the fundamental processes and their speed limits. The results were published in Physical Review Letters.
