A spin wave detective story: Researchers verify surprising behavior in a 2-D magnet
(PHYSorg.com Nanotechnology)

Researchers at the National Institute of Standards and Technology (NIST) have discovered a surprising feature in two-dimensional (2-D) magnets, a new class of materials receiving a great deal of attention. Their finding is the first verification that a signal long thought to be due to vibrations in the lattice-the structure of the material itself-is actually due to a wave of electron spins.
