Magneto-optical images of the magnetisation distribution taken a before and b 200 μs after irradiation by a single pump pulse of wavelength 13 μm and duration ≈ 2 ps. c The switched magnetic domains isolated by subtracting the non-magnetic background. The arrows and associated colour-coding indicate the direction of magnetisation. d The calculated impact of a single pump pulse on the magnetisation, obtained via micromagnetic simulations. In b and d, the dashed green line indicates the half-maximum intensity level of the pump pulse.
