Coherent ultrafast magnetism induced by femtosecond laser pulses

Femtosecond laser pulses can demagnetize ferromagnetic metallic thin films on an ultrafast timescale. Studying how a single optical pulse interacts with a magnetic film now provides a better understanding of this so-called femtomagnetism.

Quasi-static strain governing ultrafast spin dynamics

Ultrafast Sagnac interferometer provides direct access to the lattice dynamics in magnetic materials. The authors leveraged light-matter interaction to unveil the intertwined role of strain and thermal effects on the spin dynamics of ferromagnets.
