of Utah, Salt Lake City, have built the first organic spin valves that integrate organic semiconductor electronics with spintronics.
The organic spin valves resulted from the Utah-based physicists' plan to demonstrate that the production of a spin valve with an organic semiconductor, instead of a standard semiconductor, is feasible.
Using 8-hydroxyquinoline aluminum (Alq3), the scientists sandwiched the organic semiconductor between two metallic layers--one consisting of lanthanum strontium manganese oxide, the other of cobalt--to build three-layer organic spin valves.
What's new: Organic spin valves that change an electrical current's flow.
An old technology has recently been gathering a lot of strange new names--spectral hole burning, 4-D optics, cubing, spin valves
, giant magnetoresistance, and photorefractive polymer holograms, among others.
