(color online) Magnetic susceptibility measurements of CeSb₂ with H || [010]. (a1) Side view of the crystal structure of CeSb₂. (a2) top view of crystal surface of CeSb₂ along [001] direction. (a3) LEED pattern for the as-grown facet of CeSb₂ single crystal. The red arrows indicate the in-plane [100] and [010] directions. (b)–(c) Zero-field cooling (ZFC) magnetic susceptibility of CeSb₂ with different magnetic fields along [010] direction. The insert in Fig. 2(b) is the results of the ZFC and FC magnetic susceptibility measurements. (d) Magnetization isotherms for CeSb₂ at different temperatures with H || [010]. The curves in Fig. 2(d) are shifted for a better view.
