Spin-orbit driven $J_{e f f} = 1/2$ magnetism in a d $^{7}$ triangular-lattice monolayer cobaltate

Ritwik Das, Soumen Basak, Mohammad Rezwan Habib +1

Recent theoretical and experimental advances have identified cobaltates with a high-spin $d^{7}$ electronic configuration as promising hosts for spin-orbit entangled $J_{e f f} = 1/2$ …

Magnetization-Tunable Topological Phase Transitions in Ferromagnetic Kagome Monolayers of Co $_{3}$ X $_{3}$ Y $_{2}$ ( $X = Sn, Pb$ ; $Y = S, Se$ )

Ritwik Das, Arkamitra Sen, Indra Dasgupta

The quantum anomalous Hall effect in magnetic kagome materials has emerged as a versatile platform for dissipationless electronic and spintronic devices. In this work, we demonstra…
