Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

Advanced Materials, Volume 38, Issue 21, 13 April 2026.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

Photoinduced Picosecond‐Scale Radial Current for Generating and Converting Spin Textures

Nanophotonics, Volume 15, Issue 7, 13 April 2026.
A picosecond‐scale vector electrical current is generated and applied to generate and convert spin textures. Four target quasiparticle types with different topological states are generated with ultrafast speed (< 50 ps). Besides, the controlled transitions between these spin textures are achieved. ABSTRACT Magnetic skyrmions are topologically protected

Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, Volume 5, Issue 3, March 2026.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.

Néel Tensor Torque in Polycrystalline Antiferromagnets

Advanced Materials, Volume 38, Issue 9, 12 February 2026.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a

Excitation of Spin Waves in Ferrimagnetic Alloy via Optical Transient Grating Spectroscopy

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
The study demonstrates an all‐optical method for exciting and detecting standing spin waves in a ferrimagnetic thin film using the Transient Grating technique. By using polarization‐sensitive detection, we separate magnetic and thermoelastic dynamics.

Theory of Ultrafast Demagnetization after Femtosecond Laser Pulses

Acta Physica Polonica A, 2015
Experimentally it has been found that a ferromagnetic metallic lm is strongly demagnetized within few hundred fs after exposure to a fs laser pulse. The theories of this ultrafast demagnetization are reviewed, especially the in uence of scatterings of the excited electrons at phonons and at magnons.
