Abstract
The role of spin glass as a spin current absorber was investigated by spin pumping effect in Ni81Fe19/Cu/spin glass Ag 90Mn10 trilayer structure. The spin current was pumped to the spin glass layer via the Cu layer by means of the ferromagnetic resonance of the Ni81Fe19 layer. The damping constant of the ferromagnetic layer reflecting the intensity of the spin current absorption was evaluated by fitting the spectra with Lorentzian. At low temperatures, the spin current absorption in the spin glass layer arises sharply.
