ABSTRACT
Substantial advance has recently occurred in the eld of organic magnetotransport, mainly in two directions: spintronic devices, such as organic spin valves, where spin injection, transport, and manipulation have been demonstrated; and organic light-emitting diodes, where both conductivity and
