Magnetic Field Effects on Current, Electroluminescence and Photocurrent in Alq₃ Organic Light Emitting Diodes

Authors: Govindarajan Veeraraghavan, Tho Duc Nguyen, Yu Gang Sheng, Omer Mermer, Markus Wohlgenannt

Abstract: We report on the experimental observation of large magnetoresistance in Alq3 organic light-emitting diodes (OLEDs). Very similar magnetic field effects (MFEs) of comparable magnitude are also observed in electroluminescence and photocurrent measurements. We also report on the frequency response of the magnetoresistance effect at frequencies below 100 kHz. To the best of our knowledge, the mechanism causing these MFE is currently not known.
