|
| 摘要: 通过溶剂热的方法合成了一个具有nia拓扑结构混合价的甲酸铁铵盐，并对其进行了单晶结构和磁性表征，该化合物不仅在TN=37.2 K以下显示亚铁磁体的性质，还在大约28 K出现温度补偿磁性行为。本文首次用分子场理论对该磁体的温度补偿行为和磁结构相关性进行了详细的讨论与分析。 |

| Abstract: A mixed valence iron formate {[NH4][FeⅡFeⅢ(CHOO)6]}∞ (1) with nia topology was prepared under solv-othermal condition and structurally characterized by X-ray single crystal analysis. The results show that the title compound exhibits not only the ferrimagnetic nature with TN=37.2 K, but also magnetization sign inversion at the so-called compensation temperature ~28 K. The ferrimagnetic properties with temperature compensation behavior corresponding to definite single crystal structure are, for the first time, discussed in detail by molecular field theory.
