Abstract

We present results of nonlocal and three-terminal (3T) spin precession measurements on spin injection devices fabricated on epitaxial graphene on SiC. The measurements were performed before and after an annealing step at 150 ∘C for 15 minutes in vacuum. The values of spin relaxation length Ls and spin relaxation time τs obtained after annealing are reduced by a factor 2 and 4, respectively, ...
