Room-temperature magnetically modulated electroluminescence from hybrid organic/inorganic spintronics devices

Abstract

We report a hybrid organic/inorganic magnetic-field controlled light-emitting diode (h-OLED), in which an inorganic magnetic tunnel junction (MTJ) with large room temperature magnetoresistance is coupled to an OLED having efficient electroluminescence. In operation, the large resistance mismatch between the MTJ and OLED components is suppressed due to the non-linear I-V characteristic of the OLED. This leads to ∼80% giant magneto- electroluminescence at room temperature with emission in the red, green, and blue spectral ranges. © 2013 AIP Publishing LLC.
