(a) Crystal structure of GdScO₃ in space group Pbnm, where a Gd³⁺ ion is surrounded by eight distorted ScO₆ octahedrons. (b) T dependence of specific heat C_p(T). (c) T dependence of magnetic susceptibility χ(T) in an applied magnetic field of 0.3 T parallel to the a, b, and c axes, respectively. The inset: χ(T) near the AFM transition. (d) T dependence of inverse magnetic susceptibility 1/χ(T) with 0.3-T magnetic field along the c axis. The blue solid line is the fit using the Curie–Weiss law above the transition temperature.
