The advent of pump-probe spectroscopy techniques paved the way to the exploration of
ultrafast dynamics of electrons and phonons in crystalline solids. Following photo-absorption …

We review the phenomenology of light-induced ultrafast magnetization dynamics, with
emphasis on metallic compounds. The interaction of femtosecond laser pulses with …

This year the discovery of femtosecond demagnetization by laser pulses is 20 years old. For
the first time, this milestone work by Bigot and coworkers gave insight directly into the time …

Laser-induced terahertz spin transport (TST) and ultrafast demagnetization (UDM) are
central but so far disconnected phenomena in femtomagnetism and terahertz spintronics …

The evolution of the electronic band structure of the simple ferromagnets Fe, Co, and Ni
during their well-known ferromagnetic-paramagnetic phase transition has been under …

We study ultrafast magnetization quenching of ferromagnetic iron following excitation by an
optical versus a terahertz pump pulse. While the optical pump (photon energy of 3.1 eV) …

Using specially engineered structures to tailor the optical absorption in a metallic multilayer,
we analyze the magnetization dynamics of a Co/Pt multilayer buried below a thick Cu layer …

The interaction between ultrafast lasers and magnetic materials is an appealing topic. It not
only involves interesting fundamental questions that remain inconclusive and hence need …

We theoretically investigate laser-induced spin transport in metallic magnetic
heterostructures using an effective spin-transport description that treats itinerant electrons …

It has long been known that ferromagnets undergo a phase transition from ferromagnetic to
paramagnetic at the Curie temperature, associated with critical phenomena such as a …
