NanoTechnology, Storage Bits For Future Computers

Abstract:
In the family of Prussian blue, there is a compound that can act as a switch: it is not magnetic at the outset, but it can become magnetized by the effect of light and return to its initial state by heating. Researchers of the Institute of Molecular Chemistry and Materials of Orsay (CNRS/University of Paris XI) and the Laboratory of Inorganic Chemistry and Molecular Materials (CNRS/University of Paris VI) showed that this change of state is due to the collective modification of the position of the atoms, induced by light. Such compounds, which can memorize binary information, could be used as storage bits for future computers. This work was presented in the journal Angewandte Chemie International Edition (after the online publication of January 9, 2007).
