Switchable nano magnets
From
Research group at Kiel University switches magnetism of individual molecules
Using individual molecules instead of electronic or magnetic memory cells would revolutionise data storage technology, as molecular memories could be thousand-fold smaller. Scientists of Kiel University took a big step towards developing such molecular data storage. They succeeded in selectively switching on and off the magnetism of individual molecules, so-called spin-crossover complexes, by electrons. The interdisciplinary study is part of the Collaborative Research Centre 677 “Functions by Switching”, which is funded by the German Research Foundation (DFG). The results prove that it is technically possible to store information using molecules.
