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.
