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 …

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 …

Understanding the transfer of spin angular momentum is essential in modern magnetism
research. A model case is the generation of magnons in magnetic insulators by heating an …

When exciting a magnetic material with a femtosecond laser pulse, the amplitude of
magnetization is no longer constant and can decrease within a time scale comparable to the …

Optical manipulation of magnetization with femtosecond laser pulses has opened a new
paradigm shift in magnetization and spin dynamics. Since the very first demonstration of …

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

Interfaces in heavy metal (HM)-antiferromagnetic insulator (AFI) heterostructures have
recently become highly investigated and debated systems in the effort to create spintronic …

New methods to induce magnetization switching in a thin ferromagnetic material using
femtosecond laser pulses without the assistance of an applied external magnetic field have …

The surprising discovery of ultrafast demagnetization—where the electric field of a
femtosecond laser pulse interacts with electrons of a ferromagnetic (FM) layer to cause its …
