Temperature dependence of the magnetic susceptibility χ of Ni₃Sb (a), Ni₅Sb₂ (b), NiSb (c), and NiSb₂ (d) measured with an applied field of 1 T. The measured data points are presented as unfilled circles. The solid lines are fits to the modified Curie–Weiss law with parameters given in Table 4 . The arrow in Fig. 5(a) indicates the Curie temperature determined from the fit. The inset in Fig. 5(a) shows the ( χ – χ ₀)⁻¹ versus the T plot for Ni₃Sb. The unit 1 Oe = 79.5775 A·m⁻¹.
