| 中文摘要 | A series of Ga doping perovskite cobaltite La(2/3)Sr(1/3) (Co(1-y)Ga(y))O(3) (y = 0, 0.1, 0.2, 0.3, and 0.4) are prepared by the standard solid-state reaction method. Their magnetic properties and Co ions spin state transitions are studied. Upon doing, no appreciable structure changes can be found. However, the corresponding Curie temperature sharply decrease and the magnetization is greatly reduced, indicating that Ga doping destroys the ferromagnetics interaction in the system. In addition, the high temperature magnetization data flow the Curie-Weiss law. At least one kind of Co ions (Co(3+) or Co(4+)) favours the mixed spin state, and most Co ions are at the lower spin state (low and intermediate state). With increasing Ga content, more Co ions transit to the higher spin state. |
