Abstract

We measure spin transport in high mobility suspended graphene (? ??? 105cm2/(V s)), obtaining a (spin) diffusion coefficient of 0.1 m2/s and giving a lower bound on the spin relaxation time (??s ??? 150 ps) and spin relaxation length (?s = 4.7 ?m) for intrinsic graphene. We develop a theoretical model considering the different graphene regions of our devices that explains our experimental data.
