One of the new challenges in using plastics (and other organic semiconductors) for electronics is using their intrinsic magnetic field dependence. While electrons hop between localized sites, an intriguing interplay arises between the applied magnetic field and local hyperfine fields resulting from the surrounding hydrogen (see schematic illustration on the cover). As a consequence, a sizable room-temperature magnetoresistance at surprisingly low magnetic fields arises. Recent activities are aimed at trying to understand the underlying microscopic mechanisms, and exploring potential applications. Moreover, spin transport in these type of materials, which is crucial for the proper functioning of organic spin valves, can be understood using similar mechanisms. For more details see the Feature Article by Wiebe Wagemans and Bert Koopmans on pp. 1029-1041.
