DOI: 10.1002/adom.202500210
Abstract: Noncollinear antiferromagnets (AFMs) are promising candidates for next‐generation spintronic devices due to their terahertz (THz) magnetic resonance, robustness against external field interferences, and strong magneto‐optical responses. Using femtosecond laser excitation, spin current generation and THz… read more here.

Ultrafast Spin Dynamics beyond s‑Wave Magnets: A Universal Polarization Dependence
Sign Up to like & getrecommendations! Published in 2025 at "Nano Letters"
DOI: 10.1021/acs.nanolett.5c04475
Abstract: Symmetry and hybridization yield anisotropic but nodal-less Fermi surfaces in s-wave ferromagnets (FMs) and antiferromagnets (AFMs), while they produce distinct momentum-space nodes in altermagnets (AMs). Both drive anisotropic femtosecond magnetization dynamics, but this link remains… read more here.

DOI: 10.1039/d4sc04607b
Abstract: Carbene-metal-amide (CMA) complexes are appealing emitters for organic light-emitting diodes (OLEDs). However, little is known about silver(i)-CMA complexes, particularly electroluminescent ones. Here we report a series of Ag(i)-CMA complexes prepared using benzothiophene-fused carbazole derivatives as… read more here.
