A rechargeable spin battery

With an increased interest in spin logic devices compatible with the existing semiconductor technology, manipulating electron spins in nonmagnetic semiconductors has been one of the most active research directions in spintronics, promising smaller, faster, less power-consuming information-processing and communication devices. …

Duke creates new magnetic material atom by atom

Material scientists have predicted and built two new magnetic materials, atom-by-atom, using high-throughput computational models. The success marks a new era for the large-scale design of new magnetic materials at unprecedented speed. Although magnets abound in everyday life, they are …

Vacuum airship would work in thin atmosphere of Mars

Researchers propose to overcome some of the limitations of current technologies for Mars exploration and even extend current operational capabilities by introducing the concept of a vacuum airship. This concept is similar to a standard balloon, whereas a balloon uses …
