Two-dimensional Van der Waals ferromagnets have gathered a lot of interest over the last years due to their low dimensionality and easy manipulation of their magnetic state. In this talk, I will present recent research on magnetisation fluctuations in 2D van der Waals magnets. From one side, we show how finite size effects stabilise short-range magnetic order, which can be seen as magnetisation fluctuations. From the other side, we look at the laser-induced ultrafast magnetisation dynamics of a specific 2D van der Waals magnet, Fe3GeTe2.
