Spin-valley coupling and spin-polarized transport in a two-dimensional altermagnetic Cr2WS4 monolayer
Altermagnetism, characterized by momentum-dependent spin-splitting without net magnetization, attracts considerable attention due to its unique symmetry-governed electronic structures and potential applications in spintronic devices. Here, based on first-principles calculations, we identify Cr2WS4 monolayer as a two-di...
