Uranium computer disk

Stephen Liddle of the University of Nottingham, UK, works with molecules containing depleted uranium, the weakly radioactive residue of uranium enrichment for the nuclear industry. He and his colleagues have now synthesized a novel uranium-containing compound that retains its magnetic properties even at low temperatures. The discovery could take us a step closer to magnetic memory devices with capacities thousands of times denser than current high-end hard drives. Of course, marketing a uranium hard drive would be difficult, so analogs that use alternative heavy metals are now under investigation.
