In article number 1808298 , Giovanni Vignale, Deepak K. Singh, and co‐workers demonstrate a one‐to‐one correspondence between the colossal enhancement in electrical conductivity in applied magnetic field and magnetic charge crystallization of a two‐dimensional magnetic material in the form of a triangular Wigner crystal state (blue triangular structure) in a Nd‐honeycomb lattice. The neutron reflectometry measurement (green‐yellow pattern) on BL‐4A beamline at ORNL constitutes key evidence of this novel effect. Image credit: Oak Ridge National Laboratory/Jill Hemman.
