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.
Measurements at grazing incidence and reflectivity have been carried out to quantify the surface roughness in systems of spin valves [26].
Measurements of the resonance condition as a function of applied field direction are valuable for determining magnetic anisotropy energies and coupling between magnetic layers in multilayer structures such as the spin valves that are used as the active elements of read heads in modern disk drives.
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.
