artificial crystals. The crystal's structural length scales may range from nano-(light) up to …

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 …

Magnetoresistive (MR) sensors have been identified as promising candidates for the
development of high-performance magnetometers due to their high sensitivity, low cost, low …

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

We propose a semiclassical model for femtosecond laser-induced demagnetization due to
spin-polarized excited electron diffusion in the superdiffusive regime. Our approach treats …

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

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 …

Laser pulses induce spin-selective charge flow that we show to generate dramatic changes
in the magnetic structure of materials, including a switching of magnetic order from …

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