An antiferromagnet emits spin currents when time-reversal symmetry is broken. This is
typically achieved by applying an external magnetic field below and above the spin-flop …

The advent of free electron lasers has opened the opportunity to explore interactions
between extreme ultraviolet (EUV) photons and collective excitations in solids. While EUV …

Nanoscale heterostructure design can control laser-induced heat dissipation and strain
propagation, as well as their efficiency for driving magnetization precession. Here, we …

Direct light-spin interactions, induced by spin-orbit coupling (SOC), enable ultrafast spin
manipulation through coherent spin excitation, which is universal in magnetic materials due …

Laser-driven electron transport across a sample has garnered enormous attentions over
several decades, as it provides a much faster way to control electron dynamics. Light is an …

Ultrafast optically excited ferromagnetic (FM)/nonmagnetic (NM) multilayer heterostructures
have been demonstrated recently as efficient, high-power, and broadband sources of …

By ultrafast x‐ray diffraction (UXRD), it is shown that the laser‐induced magnetostructural
phase transition in FeRh nanoislands proceeds faster and more complete than in …

The increasing demand for denser information storage and faster data processing has
fueled a keen interest in exploring spin currents up to terahertz (THz) frequencies. Emergent …

Nanoscale magnetic patterning can lead to the formation of a variety of spin textures,
depending on the intrinsic properties of the material and the microstructure. Here we report …

We use ultrafast x-ray diffraction and the polar time-resolved magneto-optical Kerr effect to
study the laser-induced metamagnetic phase transition in two FeRh films with thicknesses …
