Query: Giant Nonlocality near the Dirac Point in Graphene   Transport measurements have been a powerful tool for uncovering new
electronic phenomena in graphene. We report nonlocal measurements performed in
the Hall bar geometry with voltage probes far away from the classical path of
charge flow. We observe a large nonlocal response near the Dirac point in
fields as low as 0.1T, which persists up to room temperature. The nonlocality
is consistent with the long-range flavor currents induced by lifting of
spin/valley degeneracy. The effect is expected to contribute strongly to all
magnetotransport phenomena near the neutrality point.
