The organic magnetoresistance of aluminium tris(8-hydroxyquinoline) based organic light-emitting diodes has been modeled using the triplet polaron interaction coupled with exciton dissociation. We have demonstrated that each of the processes is proportional to the exciton concentration over a wide range of operating conditions for a number of devices with a wide range of layer thicknesses. This work demonstrates that using a magnetic field to perturb the operation of a working organic device isdoi:10.1103/physrevb.86.075206 fatcat:a77i5fo7r5exzciy3syapybyly
