From: Giant Hall effect in a highly conductive frustrated magnet GdCu2
a Schematic of crystal structure of GdCu2. The black lines show an orthorhombic unit cell. b Schematic of distorted triangular lattices of Gd atoms as viewed from the b-axis for the top layer (y = 0.75) and the bottom layer (y = 0.25). The magnetic moments with 120° cycloid propagation along the a-axis and anti-parallel stacking along the b-axis are drawn with red arrows. c Temperature (T) dependence of magnetic susceptibility χ = M/H at 1 T (blue line). The inverse susceptibility χ−1 (green symbols) is fitted with the Curie-Weiss law above 150 K (θp = 10.9 K, μeff = 8.59 μB/Gd). d Temperature dependence of longitudinal conductivity σxx at zero field. e Magnetic field (H) dependence of magnetization M (blue line) and its field derivative dM/dH (green line) at 2 K. f Magnetic field dependence of Hall conductivity σxy at 2 K.
