Nonlinear Extension of the Dynamical Linear Response of Spin: Extended Heisenberg Model

We introduce a new extended Heisenberg model that contains orbital-dependent spins together with the retarded effects of spin torque. The model is directly derived from the dynamical linear response functions on the transversal spin fluctuation. Our model allows us to address effects that are not ac...
