Abstract
We report the successful extraction of spin-polarized current from the organic-based room temperature ferrimagnetic semiconductor (, TCNE: tetracyanoethylene; , , ) and its subsequent injection into a light-emitting diode. The spin current tracks the magnetization of , is weakly temperature dependent, and exhibits heavy-hole–light-hole asymmetry. This result has implications for room temperature spintronics and the use of inorganic materials to probe spin physics in organic and molecular systems.
