Measurements of the effect of a magnetic field on the light output and current through an organic light-emitting diode made with deuterated aluminum tris(8-hydroxyquinoline) have shown that hyperfine coupling with protons is not the cause of the intrinsic organic magnetoresistance. We suggest that interactions with unpaired electrons in the device may be responsible.
