Abstract:

The classical Landau-Lifshitz-Gilbert (LLG) equation has been extremely powerful in explaining and predicting magnetization dynamics of magnetic materials at temperatures far below the Curie temperature and thus LLG plays pivotal roles for today's magnetic information technology. With the next generation of magnetic storage possibly involving high temperature operations, it is highly desirable to develop theoretical tools which are capable of describing high temperature magnetization dynamics. Here, we propose an equation of motion based on quantum kinetics. Then, we address magnetization dynamics for several classes of materials including element specific dynamics for ferromagnetic and ferrimagnetic compounds.
