Mac OS X has an option to keep hard drives spinning for quick file access, or to save power and reduce noise by spinning them down when they're not in use. This can be convenient, but is rather ...
A collaborative group of researchers has potentially developed a means of controlling spin waves by creating a hexagonal pattern of copper disks on a magnetic insulator. The breakthrough is expected ...
An illustration of the two-dimensional magnonic crystal developed in this study, viewed from an oblique angle. Copper disks are periodically arranged on a magnetic garnet film. A collaborative group ...
