(Phys.org)—Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a new ...
In a pioneering effort to control, measure and understand magnetism at the atomic level, researchers working at the National Institute of Standards and Technology (NIST) have discovered a new method for manipulating the nanoscale ...
