Here a Co/Pt bilayer is simulated using a coupled micromagnetics and heat equation solver. In the heat equation a non-uniform heat source is added, simulating a focused laser pulse. A reversal field is applied during the simulation which by itself is not enough to reverse the magnetisation. As the sample temperature increases, particularly at the heat source site, the magnetisation magnitude decreases until reversal occurs. The simulation duration is 10 ns.

 

The same simulation is repeated here but with the interfacial DMI term disabled.
