Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

The interaction of subpicosecond laser pulses with magnetically ordered materials has
developed into a fascinating research topic in modern magnetism. From the discovery of …

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 …

Pulsed-laser-induced quenching of ferromagnetic order has intrigued researchers since
pioneering works in the 1990s. It was reported that demagnetization in gadolinium proceeds …

This article reviews static and dynamic interfacial effects in magnetism, focusing on
interfacially driven magnetic effects and phenomena associated with spin-orbit coupling and …

This book emerged from a close collaboration of the authors which started in the fall of 2000.
Early that year one of us (JS) had joined the Stanford faculty after spending nearly 15 years …

The quest for ultrafast magnetic processes has triggered a new field of research—
femtomagnetism: using femtosecond laser pulses to demagnetize ferromagnetic metallic …

Ultrafast laser techniques have revealed extraordinary spin dynamics in magnetic
materials,,,,, that equilibrium descriptions of magnetism cannot explain. Particularly …

Time-dependent density functional theory (TDDFT) is implemented in an all electron solid-
state code for the case of fully unconstrained noncollinear spins. We use this to study …

Femtosecond laser excitation of a ferromagnetic material creates energetic spin-polarized
electrons that have anomalous transport characteristics. We develop a semiclassical theory …
