First-principles-based search for emergent topological spin textures in transition-metal dichalcogenide monolayers
Yuhyun Cha, Do Hoon Kiem, Myung Joon Han
Topological spin textures such as skyrmions and bimerons offer rich physical functionalities and strong potential for future spin-based technologies. Identifying materials that hos…
Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe
Dirk Wulferding, Daehyeon An, Jiwon Choi +8
Altermagnets constitute an emerging class of magnetic materials that combine compensated antiferromagnetic order with spin-split excitations arising from crystalline symmetries. De…
Polymorphic spin ordering in a single-crystalline cobalt-doped Fe3GaTe2
Woohyun Cho, Jaehun Cha, Yoon-Gu Kang +10
A single crystalline system typically stabilizes a unique state for spin ordering below a critical temperature. Certain materials exhibit multiple magnetic states, driven by struct…
Singular Hall response from a correlated ferromagnetic flat nodal-line semimetal
Woohyun Cho, Yoon-Gu Kang, Jaehun Cha +9
Topological quantum phases have been largely understood in weakly correlated systems, which have identified various quantum phenomena such as spin Hall effect, protected transport…
