Neutron Science 085 This report features the work of Aifeng Wang and his collaborators published in Phys. Rev. B 107 , 115150 (2023). ANSTO ECHIDNA – High-resolution Powder Diffractometer • NPD • Materials Science, Chemistry, Condensed-matter Physics Fig. 2 : (a) Temperature dependence of in-plane resistivity for a LaMn 0.86 Sb 2 single crystal; the inset shows the first derivative of resistivity with respect to temperature d ρ ( T )/d T . (b) Temperature dependence of specific heat C p ( T ). Temperature-dependent magnetization M ( T ) at various magnetic fields up to 9 T for both B //c (c) and B ⊥ c (d). The insets show the data of B = 0.1 T. (e) M ( B ) curve collected at 2 K with B // c and B ⊥ c . (f) Magnetic field dependence of MR with field gradually tilted away from c -axis. [Reproduced from Ref. 4] Fig. 3 : (a) Refined neutron powder diffraction (NPD) patterns at various temperatures. (b) The magnetic structure deduced from the NPD result, where the dashed line represents the crystallographic unit cells. The magnetic unit cell is doubled along the c-axis of the crystallographic unit cell. [Reproduced from Ref. 4] References 1. Z. Qiu, C. Le, Z. Liao, B. Xu, R. Yang, J. Hu, Y. Dai, X. Qiu, Phys. Rev.
