Time evolution of three-temperature model for a large laser-fluence case Te(0) = 1.6. The critical slowing down
of the spin system is identified as the plateau in the figure. The inset defines a slowdown time τd . The smaller inset shows the magnified region in the vicinity of the maximum temperature.
