Fig. 1: Magnetic susceptibility and phase diagram of UTe₂.

a Temperature-dependence of the inversed magnetic susceptibility 1/χ of UTe₂ in magnetic fields H applied along the three main crystallographic directions a, b, and c. Inset: Temperature-dependence of the magnetic susceptibility χ for H||a, b, and c, in a log-log scale. b Low-temperature magnetic-field versus angle phase diagram of UTe₂, in fields applied along variable directions from b to a (angle ϕ) and from b to c (angle θ). Two low-temperature paramagnetic regimes and identified: correlated paramagnetism (CPM) and polarized paramagnetism (PPM). SC1 is the low-field superconducting phase, and SC2 and SC-PPM are the superconducting phases induced by magnetic fields H||b and H tilted by 27 ± 5° from b in the (b, c) plane, respectively. H_c,2 is the critical superconducting field and H_m is the metamagnetic field. Data from by Ran et al.³³ and Knebel et al.³⁷ were plotted in this Figure.
