Abstract
Atomistic and mesoscopic-scale spin dynamics have proven to be a powerful tool for studying magnetization dynamics on the sub-picosecond time-scale. These approaches are ideal for combining different length and time-scales. In this paper we focus on atomistic spin dynamics in the ultrafast regime, in particular on recent results of heat-induced switching in the transition-metal rare-earth ferrimagnets.
