Abstract
Here we consider the mechanism responsible for the ultrafast heat-induced switching of the magnetization in ferrimagnetic rare-earth—transition metal films. This switching is found to follow a counterintuitive pathway via a ferromagnetic, which crucially depends on the angular momentum balance of the two opposite sublattices.
