Extended Data Figure 1: Photographs, XRD patterns and field dependence of the magnetization of YbMgGaO4.
From: Evidence for a spinon Fermi surface in a triangular-lattice quantum-spin-liquid candidate
a, Photographs of a representative YbMgGaO4 single crystal. b, XRD pattern of a YbMgGaO4 single crystal from the cleaved surface. c, Rocking curve of the (0, 0, 18) peak. The horizontal bar indicates the instrumental resolution. d, Laue pattern of the YbMgGaO4 single crystal viewed from the c axis. e, Observed (red) and calculated (green) XRD diffraction intensities of ground single crystals. The X-ray has a wavelength of 1.54 Å. The blue curve indicates the difference between the observed and calculated intensities. f, Magnetic field dependence of magnetization at T = 2 K. Fitted g factors and Van Vleck susceptibilities χVV are shown (μB is the Bohr magneton). The dashed lines are linear fits above 12 T.
