We report that neutron diffraction and magnetic susceptibility studies of orthorhombic single crystal (Sr_0.97K_0.03) MnSb₂ confirm the three-dimensional (3D) C-type antiferromagnetic (AFM) ordering of the Mn²⁺ moments at T_N = 305 ± 3 K, which is slightly higher than that of the parent SrMnSb₂ with T_N = 297 ± 3 K. Susceptibility measurements of the K-doped and parent crystals above T N are characteristic of 2D AFM systems. This is consistent with high-temperature neutron diffraction of the parent compound that displays persisting 2D AFM correlations well above T_N to at least ~ 560 K with no evidence of a ferromagnetic phase. Analysis of the de Haas–van Alphen magnetic oscillations of the K-doped crystal is consistent with hole doping.
