how to calculate dynamics of magnetizations
« on: October 7, 2020, 08:29 »
Dear Sir,
I noticed a literature "Proximity Spin–Orbit Torque on a Two-Dimensional Magnet within van der Waals Heterostructure: Current-Driven Antiferromagnet-to-Ferromagnet Reversible Nonequilibrium Phase Transition in Bilayer CrI3." Nano Letters 20.4 (2020): 2288-2295 is done by ATK. But i have no idea how to calculate dynamics of magnetizations in Fig. 5. Can you help me?
Best,
Lishu

Hi,

While QuantumATK can be used to calculate parameters entering the LLG equation (spin transfer torque, Gilbert damping, magnetic moments, etc.) we currently do not have any modules for calculating the magnetization dynamics by solving the LLG equation. This part was implemented by the authors them-self in the cited paper. Notice also that the calculation of spin-orbit torque was implemented by the authors them-self.
