我们研究了它的磁性，并建立了详细的磁相图.用，将磁性氧化成磁性，将反铁磁绝缘基态变成铁磁绝缘（FM）。混合价态对FM行为是必不可少的。居里温度在K处有一个平台，FM相关在K附近增强最大。替代由于磁化子的稀释而抑制FM相关。我们的研究结果将为基化合物的磁电相控制提供有用的信息。
We have investigated the magnetic properties ofwithand established a detailed magnetic phase diagram. Substitution ofwith, which oxidizes magneticinto nonmagnetic, turns the antiferromagnetic insulating ground stateinto the ferromagnetic (FM) insulating one. Themixed valence is indispensable for the FM behavior. In, the Curie temperaturehas a plateau atK, and the FM correlation is most enhanced around. Insubstitution suppresses the FM correlation due to the dilution of magneticions. Our present results would provide useful information for magnetoelectric phase control of-based compounds.
