Ultrafast Spin Dynamics in Nickel by jianwu167 is a document available to read on EtoBox.
This study investigates ultrafast spin dynamics in ferromagnetic nickel using femtosecond optical pulses. The results show a rapid drop in magnetization within the first picosecond, with distinct electron and spin dynamics observed for delays of 0-5 ps, described by a model of three interacting reservoirs (electrons, spins, and lattice). The findings indicate that the spin temperature can rise significantly during the relaxation of electrons to the lattice, suggesting implications for magneto-optic applicat
