This review discusses the recent studies of magnetization dynamics and the role of angular
momentum in thin films of ferrimagnetic rare-earth–transition metal (RE–TM) alloys, eg …

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 …

The discovery of spin-transfer torque (STT) enabled the control of the magnetization
direction in magnetic devices in nanoseconds using an electrical current. Ultrashort optical …

Ferromagnetic or antiferromagnetic spin ordering is governed by the exchange interaction,
the strongest force in magnetism,,,. Understanding spin dynamics in magnetic materials is …

The question of how, and how fast, magnetization can be reversed is a topic of great
practical interest for the manipulation and storage of magnetic information. It is generally …

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

Topological states of matter exhibit fascinating physics combined with an intrinsic stability. A
key challenge is the fast creation of topological phases, which requires massive …

Using time-resolved single-shot pump-probe microscopy we unveil the mechanism and the
time scale of all-optical magnetization reversal by a single circularly polarized 100 fs laser …

We propose a general theoretical framework for ultrafast laser-induced spin dynamics in
multisublattice magnets. We distinguish relaxation of relativistic and exchange origin and …
