Interface between insulators enables information transport by spin
(PHYSorg.com Physics)

Modern computer technology is based on the transport of electric charge in semiconductors. But this technology`s potential will be reaching its limits in the near future, since the components deployed cannot be miniaturized further. But, there is another option: using an electron`s spin, instead of its charge, to transmit information. A team of scientists from Munich and Kyoto is now demonstrating how this works.
