  author={Mara Strungaru and Matthew O. A. Ellis and Sergiu Ruta and Oksana Chubykalo-Fesenko and Richard F. L. Evans and Roy. W. Chantrell},
A unified model of molecular and atomistic spin dynamics is presented enabling simulations both in microcanonical and canonical ensembles without the necessity of additional phenomenological spin damping. Transfer of energy and angular momentum between the lattice and the spin systems is achieved by a coupling term based upon the spin-orbit interaction. The characteristic spectra of the spin and phonon systems are analyzed for different coupling strength and temperatures. The spin spectral…

Collective dynamics in atomistic models with coupled translational and spin degrees of freedom

Using an atomistic model that simultaneously treats the dynamics of translational and spin degrees of freedom, we perform combined molecular and spin dynamics simulations to investigate the mutual

Reinventing atomistic magnetic simulations with spin-orbit coupling

We propose a powerful extension to the combined molecular and spin dynamics method that fully captures the coupling between the atomic and spin subsystems via spin-orbit interactions. Moreover, the

Spin-lattice-electron dynamics simulations of magnetic materials

We develop a dynamic spin-lattice-electron model for simulating the time-dependent evolution of coupled spin, atomic, and electronic degrees of freedom in a magnetic material. Using the model, we

This work solves semiclassical Langevin spin-dynamics equations, and applies the fluctuation-dissipation theorem, to derive an equation for the temperature of a spin ensemble, expressed in terms of dynamic spin variables.

Atomistic spin dynamic method with both damping and moment of inertia effects included from first principles.

A generalized equation of motion is derived for the magnetization dynamics in the semiclassical limit, which is nonlocal in both space and time and retained a generalized Landau-Lifshitz-Gilbert equation, also including the moment of inertia.

A quantum mechanical model is used to derive a generalized Landau-Lifshitz equation for a magnetic moment, including fluctuations and dissipation. The magnetic moment is linearly coupled to a
