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

Nonreciprocal Terahertz Propagation via InSb Topological Photonic Crystals
Addressing the challenge of high magnetic field requirements in conventional gyromagnetic materials, this article investigates indium antimonide (InSb) rod arrays operating at terahertz frequencies. By exploiting the synergy between the Voigt effect and the dispersive scaling properties, robust unidirectional propagation is achieved under a remarkably ...

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

Is There A Pure Electronic Ferroelectric?
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

MRI and Implant Safety at Low‐Field and Ultralow‐Field Strengths
ABSTRACT Despite its unequivocal value in radiological diagnosis, access to conventional high‐field MRI systems remains extremely uneven across the world. Access is particularly limited in underfunded and remote settings, due to the high cost and infrastructure requirements of MRI systems.
