(Phys.org) —A panel of experts convened by the U.S. Department of Energy has suggested that the DOE fund just one laser, rather than the two that were expected to receive funds for a new type of research facility. In contention ...
Probing magnetic materials with extreme ultraviolet radiation allows to obtain a detailed microscopic picture of how magnetic systems interact with light—the fastest way to manipulate a magnetic material. A team of researchers ...
