Abstract
The article presents the results of investigation of the giant magnetoresistance effect in a magnetic metal–organic semiconductor–non-magnetic metal structure with a magnetoresistive coefficient of ~2600%. The influence of a magnetic field on the concentration and mobility of charge carriers and the ferromagnetic–polymer potential barrier is studied. The possibility of theoretical interpretation of the investigated phenomenon based on a recently proposed model, which takes into account the effect of a hyperfine field on spin-dependent carrier hopping along the polymer chain, is considered.
