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 ...

Hexagonal boron nitride has a layered crystalline structure in a hexagonal lattice arrangement composed of alternating boron and nitrogen atoms held together by strong covalent bonds. This structure ...

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 ...
