Spin diffusion length in Au wires and films investigated by weak antilocalization measurements

2020 
Working with weak antilocalization measurements on Au wires and films grown by molecular beam epitaxy and dc magnetron sputtering with fine-tuned electron scatterings, we investigated the spin diffusion length in Au mesoscopic structures in quasi-1D and quasi-2D regimes. The result shows that the spin relaxations in both Au quasi-1D wires and quasi-2D films follow the Elliott–Yafet mechanism regardless of the deposition method. Furthermore, we observed a dimensionality behavior of spin diffusion between the quasi-1D and quasi-2D cases following the generalized Einstein's equation on Brownian motion.
