Firstly, we discuss the spin torque and domain wall motion in two-dimensional limits of the ferromagnetic Kagome lattice. [1] Second, we extend the 2D model to thin films of Kagome-lattice shandite, [2] which are more realistic. All of the two models cause non-adiabatic spin-transfer torque on the domain wall reducing the intrinsic threshold current. These results and discussions suggest a good comparison between ideal models and realistic models in terms of spin torques in topological materials.
