Spin-filter effect demonstrated in an organic molecule

(Before It's News)

Researchers from the University of Arizona and the University of Kaiserslautern demonstrated how organic molecules interact with the magnetic electrode in so-called spintronic devices. Organic Spintronics is interesting because organic semiconductors have several advantages as they can be manufactured cheaply and can be processes at low temperatures.

Using ultra-fast, time-resolved measurements probing the interface between an organic semiconductor and a magnetic metal, the researchers showed that spin controls the time an electron stay trapped in the molecule. This shows that the organic molecule interacts with the magnetic electrode in a spin-dependent way. This is called a spin-filter effect.
