Magnetic data bit stored on single atom
In the drive to cram ever more information into handy data-storage devices, researchers have reduced the size of a bit of data to the ultimate limit—a single atom (Nature 2017, DOI: 10.1038/nature21371). The study may lead to ways of increasing the data-storage density of devices such as computer hard drives, in which information is encoded in magnetic materials.
To store data on a computer hard drive, a device known . . .
