摘要：
In this paper, the rare earth cobaltite Nd1-xSrxCoO3 (0.1 <= x <= 0.5) samples were prepared using conventional solid state reaction method. Magnetization and spin state of cobalt of sample were systematically investigated. The experimental result suggests that magnetization and the Curie temperature increase sharply with increasing Sr content. The Curie-Weiss fit shows that most of the Co3+ ions are in the intermediate spin state and the Co4+ ions are in low spin for x=0.5. Furthermore, our study confirms that spin-state transition take place in Nd1-xSrxCoO3.
