Figure 1
Temperature dependence of the magnetic susceptibility χ = M/H for magnetic fields applied parallel (\({\chi }_{\parallel }\)) and perpendicular (χ ⊥) to the c-axis. Here, M is the magnetisation and H is the magnetic field. The inset displays the inverse magnetic susceptibility as a function of temperature. The solid lines represent fits of a Curie-Weiss law, χ(T) = C/(T − θ W), to \({\chi }_{\parallel }(T)\) and χ ⊥(T) in the temperature interval 300 K ≤ T ≤ 400 K and 350 K ≤ T ≤ 400 K, respectively.
