Ultrafast Control of Néel Vector in Collinear Antiferromagnet MnPt. [PDF]

Adv Sci (Weinh)
Direct evidence of ultrafast manipulation of the antiferromagnetic order parameter (Néel vector) in an exchange bias system is demonstrated using terahertz (THz) emission spectroscopy. Laser‐induced torque cants the Néel vector in the collinear antiferromagnet MnPt, generating a transient magnetic moment that produces THz radiation. This study provides

Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

Small, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Picosecond Stabilization of Transferred Charge Carriers at Plasmonic Metal–Molecule Interfaces

Angewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
Charge and heat transfer processes between plasmonic nanoparticles and adsorbed moleculal monolayers are observed using ultrafast infrared spectrocopy. Analysis of free carrier absorption and vibrational signals indicates that overflowing charge carriers are stabilized, extending their lifetime to several picoseconds.

Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...
