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 ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, amongst other things, because they lead ...

Engineers at Columbia University, NY, USA, and theoretical collaborators at the Max Planck for the Structure and Dynamics of Matter, Hamburg, Germany, have found that pairing laser light to crystal ...

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 ...
