Abstract
In order to obtain some informations on the electronic structure of Mn 4 N, the magnetic properties of Mn 4 N compounds, partially substituted by In and Sn respectively, are studied by a newly devised magnetic torsion balance. These compounds show very complicated temperature- and composition-dependences of saturation magnetization and have the magnetic susceptibilities nearly independent of temperature at far above the Curie temperatures. Moreover, the composition dependence of the magnetic moment varies remarkably with the species of substituent metals. These facts may be explained in terms of an intuitive band scheme which leads to the variation of the magnetic moment on each sublattice with temperature. The band scheme of γ-Mn is also discussed in connection with that of Mn 4 N
为了获得有关 Mn 4 N 电子结构的一些信息，我们利用新设计的磁扭转平衡研究了分别被 In 和 Sn 部分取代的 Mn 4 N 化合物的磁特性。这些化合物的饱和磁化显示出非常复杂的温度和成分依赖性，并且在远高于居里温度时，其磁感应强度几乎与温度无关。此外，磁矩的成分依赖性随取代金属的种类而显著变化。这些事实可以用一个直观的能带方案来解释，该方案导致每个子晶格上的磁矩随温度而变化。γ-锰的能带方案还与锰 4 N 的能带方案进行了讨论。
