摘要：

We report detailed magnetization studies of single-crystal samples of La0.9Sr0.1MnO3. This perovskite compound undergoes a paramagnetic-insulator to ferromagnetic-insulator transition around 150 K and then a transition to a canted antiferromagnetic insulating state at 110 K [H. Kawano et al., Phys. Rev. B 53. R14 709 (1996)]. Magnetization data show a strong anomaly in the temperature range from 105 to 118 K. There is a sharp increase in magnetization around 110 K and the temperature of this transition increases with an increase in magnetic field. The field dependence of the magnetization suggests a field-induced magnetic transition in the temperature range of 105-118 K with a large magnetic entropy change.
