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

Magnetic phenomena are ubiquitous in nature and indispensable for modern science and
technology, but it is notoriously difficult to change the magnetic order of a material in a rapid …

The study and control of magnetic materials using ultrashort laser pulses is of great interest
both from a fundamental point of view and for potential applications in the technology of …

High-harmonic generation (HHG) traditionally combines~ 100 near-infrared laser photons to
generate bright, phase-matched, extreme ultraviolet beams when the emission from many …

The interplay of light and magnetism allowed light to be used as a probe of magnetic
materials. Now the focus has shifted to use polarized light to alter or manipulate magnetism …

Uncovering the physical mechanisms that govern ultrafast charge and spin dynamics is
crucial for understanding correlated matter as well as the fundamental limits of ultrafast spin …

We introduce ultrafast low-energy electron diffraction (ULEED) in backscattering for the
study of structural dynamics at surfaces. Using a tip-based source of ultrashort electron …

Recent advances in high-order harmonic generation have made it possible to use a tabletop-
scale setup to produce spatially and temporally coherent beams of light with bandwidth …

The study of ultrafast dynamics in magnetic materials provides rich opportunities for greater
fundamental understanding of correlated phenomena in solid-state matter, because many of …

The underlying physics of all ferromagnetic behavior is the cooperative interaction between
individual atomic magnetic moments that results in a macroscopic magnetization. In this …
