ARPES and DFT show that at x=1/3 in Fe_x NbS2, Fe 3d_z2 bands lose coherence above the critical doping, collapsing Fe-Nb hybridization and suppressing out-of-plane Fe-Fe exchange to drive the stripe-to-zigzag antiferromagnetic transition.

KV2Se2O-based altermagnetic tunnel junctions show transmission that oscillates with SrTiO3 layer number due to interface parity, yielding a predicted TMR of 4.6×10^7% at four layers.
Spinon-holon parton theory for ARPES response of altermagnetic Mott insulators predicts renormalized bandwidth and spin-split spectra with spin-dependent weights, confirmed via tensor network simulations.
ESR reveals flipping g-anisotropy, linewidth broadening, and susceptibility kink indicating two distinct BETS chains and possible altermagnetic order in κ-(BETS)₂Mn[N(CN)₂]₃.
NV-center quantum relaxometry encodes momentum-space anisotropy of altermagnetic spin diffusion, enabling local distinction from antiferromagnets.
Ab initio plus analytical analysis shows multiorbital Mn2+ character produces dominant antiferromagnetic nearest-neighbor exchange in La2O3Mn2Se2 altermagnet, yielding identifiable magnon signatures.
