Switching the Magnetism of Individual Molecules Could Shrink Size of Memory 1000x
Using a scanning tunneling microscope, Kiel scientist Dr. Thiruvancheril Gopakumar was able to switch individual molecules between two magnetic states. Despite their dense packing in a molecular layer, he was able to target individual molecules for switching.
The next step will be to switch molecules with light instead of electrons and at higher temperatures.
