Low-temperature thermodynamic properties of single-crystalline GdSbTe. (a) Temperature dependence of the magnetic susceptibility measured in a magnetic field of 0.1 T applied along the crystallographic c axis (triangles) and the tetragonal a–b plane (circles). (b) Temperature dependence of the specific heat.
