Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2
Advanced Science, EarlyView.Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...

Angewandte Chemie, EarlyView.Dibenzo[b,d]selenophene (DBSe) π‐core fusion enables rapid triplet–singlet interconversion while preserving the narrowband emission features of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) luminogens. Combined with peripheral donor engineering, this strategy enables systematic emission tuning from green to red, leading to highly ...

Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction
Angewandte Chemie, EarlyView.Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Advanced Science, EarlyView.A conductive ZrB2 ceramic composite strategy was developed for Mg3(Sb, Bi)2 thermoelectrics to regulate carrier transport and phonon scattering through heterointerface engineering. The 1.0 wt.% ZrB2 composite achieved enhanced room‐temperature performance, with a power factor of 28.51 µW cm−1 K−2 and a peak ZT of 1.22 at 573 K.

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets
Advanced Science, EarlyView.RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.
