Temperature-dependent magnetic susceptibilities for (a) H ‖ c and (b) H ‖ a . (c) Curie–Weiss law (red line) fitting the reciprocal susceptibility 1/ χ _c (black line), the inset shows the low temperature regime (blue line denotes 1/ χ _a). (d) Magnetic susceptibility as a function of temperature under H = 1 T, with magnetic field applied along c axis and a axis, respectively. Inset shows the scenarios of the low temperature regime.
