• Meet us on March 16 at 17:30-18:15

Content

• simulating the atomistic spin Hamiltonian
• energy minimization for magnetic textures
• atomistic LLG-dynamics
• extracting simulation parameters from a scientific paper
• calculating the skyrmion collapse barrier using the GNEB-method
• influence of a magnetic field on the FM and AFM skyrmion radius

• Monte Carlo method to characterize Curie temperature and anisotropy energy

After the Tutorial

All of the notebooks are available on GitHub. If you want to have access to the solutions you can check out the solution branch.

Additional Information

The tutorial is preceded by two lectures deriving the Atomistic Spin-Hamiltonian and how it connects to DFT results:

• 16:00–16:45 Derivation of the spin-lattice Hamiltonian - Hiroshi Katsumoto
• 16:45–17:30 Computing magnetic exchange interactions using DFT - Manuel dos Santos Dias
