Ghimire, Madhab Neupane Nature Communications https://arxiv.org/pdf/2508.12985 html The authors report that Co1/4TaSe2 is a layered altermagnet: combined ARPES and DFT show momentum-selective, g-wave spin splitting of bands below a Néel temperature of 178 K, with the splitting strongest near kz≈π/2c (measured at 55 eV) and collapsing near kz≈0 (48 eV) and above T_N. The observed momentum separation is marginally above the instrument resolution, motivating spin-resolved and transport follow-ups. https://doi.org/10.1088/1674-1056/ae9b82 doi:10.1088/1674-1056/ae9b82 Wed, 19 Aug 2026 02:48:06 GMT Kun He, Shuanghai Wang, Caitao Li, Guanqun Feng, Yu Liu, Zihao Yuan, Zixiang Chen, Linlin Xia, Feng Su, Taikun Wang, Yao Li, Jun Du, Wenqin Zou, Yonglei Wang, Yongbing Xu, Liang He Chinese Physics B abstract The paper reports deterministic, field-free spin-orbit-torque switching of perpendicular magnetization in sputtered Ta/Pt1-x(RuO2)x/Co/Ta stacks, attributed to an out-of-plane spin current from RuO2-doped Pt; the x=0.18 sample switches at Jc = 11×10^6 A/cm^2 (reduced to 5.5×10^6 A/cm^2 with Hx = 650 Oe) and harmonic Hall gives a peak damping-like efficiency ξ_DL = 0.286 at x = 0.02. https://doi.org/10.1002/adfm.77903 doi:10.1002/adfm.77903 Fri, 21 Aug 2026 16:04:32 GMT Shuo Zhang, Zijie Fu, Lixiu Guan, Yirui Du, Linyang Li, Junguang Tao Advanced Functional Materials abstract The paper proposes a symmetry-locked bilayer altermagnet that combines d-wave altermagnetic band splitting with momentum-space topology and stable real-space antiskyrmions. Strain and Néel-vector control tune between antiferromagnetic Weyl and spin-layer-polarized Hall-like phases, while matched interlayer Dzyaloshinskii–Moriya couplings produce antiskyrmion pairs whose transverse (Magnus) forces cancel, allowing strictly longitudinal current-driven motion. https://doi.org/10.2139/ssrn.7309700 doi:10.2139/ssrn.7309700 Tue, 18 Aug 2026 23:48:33 GMT Andrea Leon, Matías Torreblanca, Carmine Autieri, Jhon W. González Journal abstract The authors predict monolayer CuF2 is a two-dimensional altermagnet whose P21/c symmetry produces chiral magnon bands with topological indices (Chern numbers ±2) and cycloidal phonons; the magnon and phonon chiral responses occupy complementary regions in momentum space, tying altermagnetism to coupled spin–lattice chirality.
