摘要：

Magnetoresistance measurements have been performed on thin layers of the triphenyl-diamine derivative, N,N'-diphenyl-N,N' bis(3-methylphenyl)-(1, 1 '-biphenyl)-4,4 ' diamine (TPD). At low drive voltages, where the current transport is solely hole mediated, no magnetoresistance is observed. At higher drive voltages, where electron injection into the TPD is occurring, magnetoresistance is seen and the sign of the magnetoresistance depends on the current density in the device.
