Extended Data Fig. 5: Orientation dependent magnetism of CeSiI.
From: Two-dimensional heavy fermions in the van der Waals metal CeSiI
Temperature dependence of the magnetic susceptibility with an applied magnetic field of 1 T with the field parallel and perpendicular to the c-axis. The inset shows an optical microscope image of a CeSiI crystal with a scale bar of 100 μm. b, Curie-Weiss curve with a field of 1 T parallel to the crystallographic c-axis and the grey dashed line representing the Curie-Weiss fit with C = 0.771 emu K mol−1 (μeff = 2.48) and θ = −3 K. The expected value of C for Ce3+ is 0.804 emu K mol−1 (μeff = 2.54).
