Abstract

We report room temperature measurement of magneto-conductance (MC) and magneto-photoconductance (MPC) in copper phthalocyanine thin film. Single layer device was investigated at different angles between the magnetic field lines and the normal of device surface. The reported reduction in the negative MC as the applied bias voltage was enhanced may be due to minority charge injection at high voltage regions (bipolar). MC at 1 and 5 V were found to be −2.73 and 4.09% at 0º (100 mT) whereas at 90º (100 mT) were found to be −7.15 and 8.79%, respectively. The data suggests an anisotropic effect in MC. A similar behaviour was observed for MPC. The device shows single relaxation phenomena observed in impedance spectroscopy.
