Graphene with time-dependent spin-orbit coupling: Truncated Magnus expansion approach
A. López, A. Scholz, Z. Z. Sun +1
We analyze the role of ac-driven Rashba spin-orbit coupling in monolayer graphene including a spin-dependent mass term. Using the Magnus expansion as a semi-analytical approximatio…
Floquet spin states in graphene under ac driven spin-orbit interaction
A. López, Z. Z. Sun, J. Schliemann
We study the role of periodically driven time-dependent Rashba spin-orbit coupling (RSOC) on a monolayer graphene sample. After recasting the originally system of dynam…
Optimal time-dependent polarized current pattern for fast domain wall propagation in nanowires: Exact solutions for biaxial and uniaxial anisotropies
P. Yan, Z. Z. Sun, J. Schliemann +1
One of the important issues in nanomagnetism is to lower the current needed for a technologically useful domain wall (DW) propagation speed. Based on the modified Landau-Lifshitz-G…
Critical current under an optimal time-dependent polarization direction for Stoner particles in spin-transfer torque induced fast magnetization reversal
Z. Z. Sun, X. R. Wang
Fast magnetization reversal of uniaxial Stoner particles by spin-transfer torque due to the spin-polarized electric current is investigated. It is found that a current with a prope…
