What is Terahertz Spin Transport in Gd|Pt Stacks about?
This document investigates femtosecond spin transport in Gd|Pt stacks, revealing that the ultrafast spin Seebeck effect is the primary driving force for spin current transfer from Gd to Pt. The study shows that Gd behaves similarly to a magnetic insulator in this context, as the transient spin voltage contribution is minimal due to exchange scattering. Time-resolved photoemission experiments support these findings, indicating that the dynamics of hot majority- and minority-spin electron populations are comp
