Evidence for Dyakonov-Perel-like Spin Relaxation in Pt

Evidence for Dyakonov-Perel-like Spin Relaxation in Pt
Andrei Zholud, Haidong Zhou, Zhiling Dun, Ryan Freeman, Sergei Urazhdin
We utilize nanoscale spin valves with Pt spacer layers to characterize spin relaxation in Pt. Analysis of the spin lifetime indicates that Elliott-Yafet spin scattering is dominant at room temperature, but an unexpected intrinsic Dyakonov-Perel-like spin relaxation becomes dominant at cryogenic temp...
