Abstract
AbstractIn this contribution we review recent advances of the organic magnetic field effects, namely magneto‐conductance and magneto‐electroluminescence, in both experiment and theory. We describe a number of processes, including the polaron‐pair and triplet‐triplet pair mechanisms that are responsible for the magnetic field effects in organic semiconductor systems. For the polaron pair mechanism, we review in detail the effect of the hyperfine interaction, both isotropic and anisotropic; different g‐factors of the two polarons composing the pair; and the spin orbit interaction. The effect of the triplet‐triplet annihilation process is also analyzed. Experimental examples for each case treated theoretically are given.
