Organic Spintronics

Recently we reported the first organic spin valve made of a thin layer of Alq3 (about 20-30 nm) sandwiched between Ni and Co contacts using an array of pores about 50 nm in diameter and 5000 angstroms in length which were generated by anodization of an aluminum template. The latter is flexible and very inexpensive to fabricate. A complete description of the spin valve fabrication was reported recently in the journal Nature-Nanotechnology
S. Pramanik, C.-G. Stefanita, S. Bandyopadhyay, N. Harth, K. Garre, and M. Cahay "Spin relaxation in organic spin valves", Nature-nanotechnology, March 2007.
Some of the research was also described in some recent press release.

Below are a few pictures of Kalyan Garre and M. Cahay in the laboratory at UC where the organic spin valves were fabricated.
