Graphene Holds Promise for Spintronics
Electron spins have been predicted to align along the so-called zigzag edges
of graphene (top). In reality, this perfect order is strongly affected by
thermal excitations, thus imposing strict limitations on graphene-based
spintronic devices. Researchers are studying the theoretical general types
of spin disorder (middle and bottom) in order establish these limitations.

Graphene is a nanomaterial which combines a very simple atomic structure
with intriguingly complex and largely unexplored physics. Since its first
isolation about four years ago, researchers suggest a...
