Abstract: Temperature and field-dependent magnetizationM(T,H) measurements and neutron scatteringstudy of a single crystal CeSb2are presented. Several anomalies in magnetization curves havebeen confirmed, i.e., at 15.6 K, 12 K, and 9.8 K, respectively. These three transitions are allmetamagnetic transitions, which shift to lower temperatures as the magnetic field increases. Incontrast to the previous studies that the anomaly at 15.6 K has been suggested as paramagneticto ferromagnetic phase transition, in our measurement no hysteresis loop around zero fieldwith eitherH‖corH⊥chas been observed. The anomaly located at around 12 K isantiferromagnetic-like transition, and this turning point will clearly split into two when themagnetic fieldH2 kOe. A neutron scattering study reveals that the low temperature groundstate of CeSb2orders magnetically with commensurate propagation wave vectorsk=(−1,±1/6, 0) andk=(±1/6,−1, 0), with phase transition temperatureTC∼9.8K.
