Huge magnetoresistance in metal–organic semiconductor–metal structure

The article represents results of huge magnetoresistance effect investigation in the structure of magnetic metal–organic semiconductor–nonmagnetic metal with magnitude of $\sim$ 2600%. There are observed influence of magnetic field on concentration and mobility of charge carriers and on magnitude of ferromagnetic/semiconductor potential barrier. Theoretical interpretation is considered with previously discussed model. The model describes influence of hyperfine fields on spin selective hopping rate between the sites in the polymer
