Abstract

We investigate spin transport in diffusive graphene nanoribbons with both clean and rough zigzag edges, and long-range potential fluctuations. The long-range fields along the ribbon edges cause the local doping to come close to the charge neutrality point forming p-n junctions with localized magnetic moments, similar to the predicted magnetic edge of clean zigzag graphene nanoribbons. The ...
