Extended Data Fig. 1: Structural, magnetic and compositional characterization of MnTe2 single crystals.
From: Observation of plaid-like spin splitting in a noncoplanar antiferromagnet
a, Single-crystal X-ray diffraction results of MnTe2, showing a (001) exposed plane. Inset, a MnTe2 single crystal against a millimetre grid. b, FC and ZFC temperature dependence of magnetization with H∥(001). The magnetic transition temperature is TN = 87 K. The downturn of the ZFC M–T curve at TN signals the AFM behaviour. Inset, magnetic-field dependence of magnetization at T = 2 K. c, A typical scanning electron microscopy image of the MnTe2 single crystal and corresponding energy-dispersive X-ray spectroscopy elemental maps, indicating a homogeneous distribution of the Mn and Te elements. d, Atomic ratio of Mn and Te at the seven regions indexed in c. A ratio close to 1:2 is found in all regions, indicating a high quality of the crystals.
