where the line of constant threshold fluence in the Gaussian footprint of the laser pulse comes close to an already existing domain wall. On the other hand, we identify the presence of laser-induceddomain-wallmotion in the toggle-switching event as a further cause for local deviations from purely
deterministic toggle switching.

The reversal of magnetization at the fastest possible time scales and microscopic length scales is one of the most
sharp features created in a switching event, and (ii) laser-induceddomain-wallmotion. From our results, we cannot deduce an effect of the base temperature. Both effects can become important for optical writing of magnetic information.
