Description
Summary:The Landau–Lifshitz (LL) equation, originally proposed at the macrospin level, is increasingly used in Atomistic
 Spin Dynamic (ASD) models. These models are based on a spin Hamiltonian featuring atomic spins of
 fixed length, with the exchange introduced using the Heisenberg formalism. ASD models are proving a powerful
 approach to the fundamental understanding of ultrafast magnetization dynamics, including the prediction of the
 thermally induced magnetization switching phenomenon in which the magnetization is reversed using an ultrafast
 laser pulse in the absence of an externally applied field. This paper outlines the ASD model approach and
 considers the role and limitations of the LL equation in this context.
