“…Specifically, the dynamic characteristics of laser-induced ultrafast demagnetization and magnetization recovery processes in diverse material systems and the underlying physical mechanisms have attracted much attention [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. However, despite numerous experimental and theoretical studies [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], there are still ongoing debates surrounding the mechanism of ultrafast demagnetization.…”
