"CHIPS: Circuit-sized quantum effect observed"

Magnetic quantum effects have been harnessed for the first time at the lithographic scale of semiconductors by researchers at the National Institute of Standards and Technology (NIST) and the ISIS particle accelerator (U.K.). The international team reports chaining together 100 atoms of yttrium barium nickel oxide into a quantum spin-chain that, in effect, turned the 30-nanometer long magnetic molecule into a single element. The observed quantum effect holds the promise of using these unusually large magnetic molecules as switch, memory, or computing elements in future semiconductor circuits.
