Atomistic spin dynamics simulations are a powerful tool to describe a variety of magnetization phenomena, such as ultrafast demagnetization or switching or magnonic spin current excitation. It is based on the numerical integration of the equation of motion, the stochastic Landau-Lifshitz-Gilbert equation, of each magnetic moment on a magnetic lattice structure. This allowes for the implementation of realistic magnetic structures and complex magnetic interactions.
In this module, you will be introduced to the main concepts of this simulation technique and a basic c-code to explore magnetization dynamics simulations. You will simulate the magnetization of a magnet as function of temperature and the magnon dispersion, as well as laser-induced demagnetization.
