Strain-tunable multipiezoeffects in the Janus monolayer ${\mathrm{Cr}}_{2}\mathrm{SSe}$: Selective reversal of valley polarization and single-spin-channel anoma... (opens in new tab)

Author(s): Quan Shen, Jianing Tan, Tao Yao, Wenhu Liao, and Jiansheng DongAltermagnetism, the third class of collinear magnetic order, uniquely combines a zero net magnetization with spin-polarized bands in reciprocal space, opening new avenues for two-dimensional valleytronics and spintronics. Here, using first-principles calculations, we predict that the Janus monolayer…[Phys. Rev. B 113, 224428] Published Mon Jun 15, 2026
