(color online) Resistivity measurements of CeSb₂ with I || (001). (a) Zero-field resistivity of CeSb₂. The insert is the temperature derivative of the resistivity at low temperature. (b) and (c) Resistivity of CeSb₂ and the corresponding temperature derivative at different magnetic fields. The red triangles and vertical bars are marks of the anomalies at 6.5 K and 15.5 K, respectively. (d) Field-dependent magnetoresistance for CeSb₂ at different temperatures with H || (001). The curves in Figs. 1(b)–1(d) are shifted for a better view.
