Scattering-induced and highly tunable by gate damping-like spin-orbit torque in graphene doubly proximitized by two-dimensional magnet Cr_{2}Ge_{2}Te_{6} and monolayer WS_{2}

Autor: Klaus Zollner, Marko D. Petrović, Kapildeb Dolui, Petr Plecháč, Branislav K. Nikolić, Jaroslav Fabian

Publikováno v: Physical Review Research, Vol 2, Iss 4, p 043057 (2020)

Graphene sandwiched between semiconducting monolayers of ferromagnet Cr_{2}Ge_{2}Te_{6} and transition-metal dichalcogenide WS_{2} acquires both spin-orbit (SO) coupling, of valley-Zeeman and Rashba types, and exchange coupling. Using first principle

Effective spin-mixing conductance of topological-insulator/ferromagnet and heavy-metal/ferromagnet spin-orbit-coupled interfaces: A first-principles Floquet-nonequilibrium Green function approach

Autor: Branislav K. Nikolić, Utkarsh Bajpai, Kapildeb Dolui

Publikováno v: Physical Review Materials. 4

The spin mixing conductance (SMC) is a key quantity determining efficiency of spin transport across interfaces. Thus, knowledge of its precise value is required for accurate measurement of parameters quantifying numerous effects in spintronics, such

Scattering-induced and highly tunable by gate damping-like spin-orbit torque in graphene doubly proximitized by two-dimensional magnet Cr2Ge2Te6 and monolayer WS2

Autor: Jaroslav Fabian, Marko D. Petrović, Petr Plecháč, Branislav K. Nikolić, Kapildeb Dolui, Klaus Zollner

Publikováno v: Physical Review Research. 2

Using first-principles combined with quantum transport calculations, we predict that graphene sandwiched between insulating monolayers of Cr₂Ge₂Te₆ ferromagnet and WS₂ transition-metal dichalcogenide will exhibit spin-orbit torque (SOT) when
