Abstract:We review the emerging field of organic spintronics, where organic materials
are applied as a medium to transport and control spin-polarized signals. The
contacts for injecting and detecting spins are formed by ferromagnetic
metals, oxides, or inorganic semiconductors. First, the basic concepts of
spintronics and organic electronics are addressed, and phenomena which are
in particular relevant for organic spintronics are highlighted. Experiments
using different organic materials, including carbon nanotubes, organic thin
films, self-assembled monolayers and single molecules are then reviewed.
Observed magnetoresistance points toward successful spin injection and
detection, but spurious magnetoresistance effects can easily be confused
with spin accumulation. A few studies report long spin relaxation times and
lengths, which forms a promising basis for further research. We conclude
with discussing outstanding questions and problems.
