Manipulation of Emergent Collective Excitations via Composition Control in Mixed MPX3 Correlated 2D Antiferromagnets

Advanced Science, EarlyView.
Transition metal and chalcogen substituents are introduced into 2D antiferromagnet, NiPS3, and comprehensive photoluminescence and Raman spectroscopy studies are conducted to investigate how spin orbit entangled exciton and two magnon scattering evolve as functions of substituent concentration.

The Interplay of Magnetic Order with the Electronic Scattering and Crystal‐Field Effects in a Metallic Ferromagnet

Advanced Science, EarlyView.
The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Ultrafast Laser‐Induced Interatomic Forces in Magnetostrictive Metals

Advanced Science, EarlyView.
This study reports ultrafast changes in the interatomic forces generated by femtosecond laser excitation in magnetostrictive FeGa thin films. This ultrafast process manifests as an optical birefringence signal lasting ≈400 fs. Using a pump‐probe system, the femtosecond evolution of this nonequilibrium interatomic interaction is visualized, providing ...

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

Advanced Science, EarlyView.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Local‐to‐Nonlocal Second‐Harmonic Generation from Electrically Tunable Intersubband Polaritonic Metasurfaces

Advanced Science, EarlyView.
A local‐to‐nonlocal SHG process is demonstrated on an electrically tunable metasurface, combining an LSPR at the FF with a TM‐GMR at the SH to achieve independent dual tunability. Through modal‐overlap engineering of the proposed scheme, a high‐χ(2) MQW meta‐atom delivers strong nonlinearity while achieving 2‐DoF SH control with minimal trade‐offs ...
