- who: X. Liu from the DepartmentUniversity, Shanghai, China have published the paper: Ultrafast optical observation of spin-pumping induced dynamic exchange coupling in ferromagnetic semiconductor/metal bilayer, in the Journal: Scientific Reports Scientific Reports of 29/08/2022
SUMMARY
The last term describes the spin torque which acts on both layers as a bidirectional effect, in which αsp represents the contribution of spin pumping to the damping and m′ denotes the magnetization of_(Ga,Mn)As. The effective Gilbert damping can be obtained from the relaxation time τ, using15 α=2/[τ γ (Ha + Hb )] | Vol:(1234567890 . . .
