We have the pleasure to welcome Yaroslav Kvashnin from Uppsala University. He will give us a seminar at CEA/SPINTEC Bat 1005, room 445, entitled :
Magnetic interactions and excitations from first principles
Magnetization dynamics on the nanoscale can be well described by Landau-Lifshitz(-Gilbert) equation of motion. If properly parameterized, it enables to model magnon excitations and finite-temperature magnetic properties of real materials. Here a common practice is to assume that the atomistic magnetic moments interact with each other via Heisenberg exchange coupling (J) [read more]
