Modulation of the Transient Magnetization of an EuO/Co Bilayer Tuned by Optical Excitation
The magnetic proximity effect provides a promising way to increase the low Curie temperature (TC) of europium monoxide (EuO) toward or even above room temperature, while keeping its stoichiometry and insulating properties.

Magneto‐X Effects in Magnetic Soft Materials and Their Applications
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,

Ultrafast demagnetization dynamics of 4f antiferromagnets [PDF]
We study the ultrafast demagnetization dynamics of LnRh2Si2 (Ln = Pr, Nd, Sm, Gd, Tb, Dy, Ho) antiferromagnets after excitation by a laser pulse, using a combination of density functional theory and atomistic spin and spin-lattice dynamics simulations ...

Detection of femtosecond spin voltage pulses in a thin iron film
We present experimental evidence of a spin voltage—a difference between the chemical potentials of the two spin directions—in a thin iron film based on spin- and time-resolved photoemission spectroscopy.

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
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

Control of speed and efficiency of ultrafast demagnetization by direct transfer of spin angular momentum [PDF]
Since the discovery in 1996 that the magnetization of a nickel thin film is reduced within a few picoseconds after femtosecond-laser excitation, ultrafast demagnetization has attracted a thriving interest.

Comparative Study of Laser-Induced Ultrafast Demagnetization Dynamics in Fe, Co, and Ni [PDF]
Even twenty years after the discovery of ultrafast demagnetization of ferromagnetic materials induced by a femtosecond laser pulse there is still an ongoing debate about the mechanisms that drive the process.
