Spin transport enhancement by controlling the Ag growth in lateral spin valves

Abstract

The role of the growth conditions in the spin transport properties of silver (Ag) have been studied by using lateral spin valve structures. By changing the deposition conditions of Ag from polycrystalline to epitaxial growth, we have observed a considerable enhancement of the spin diffusion length, from ${\lambda }_{Ag}$ = 449 $\pm$ 30 to 823 $\pm$ 59 nm. This study shows that diminishing the grain boundary contribution to the spin relaxation mechanism is an effective way to improve the spin diffusion length in metallic nanostructures.
