Abstract
We report a study of the electrical bistability and bias-controlled spin valve effect in an organic device using rubrene (C42H28) as an organic semiconductor channel. The halfmetallic La0.7Sr 0.3MnO3 (LSMO) and Fe are used as the two ferromagnetic electrodes. The device displays reproducible switching between a low-impedance (ON) state and a highimpedance (OFF) state by applying different polarities of high biases. In the ON state, the device shows a spin valve effect with magnetoresistance values up to 3.75%. The observed spin valve effect disappears when the device recovers to the initial OFF state.
