在镍-铜合金的磁性研究中发现按镍原子数均分的平均原子磁矩μ(Ni)(假定μ(Cu)=0)与合金中铜的含量aCu有着直线关系。按合金中所有原子均分所得到的平均原子磁矩不具有这种直线关系,对历史上各种镍-铜合金的电子结构分析之后,我们提出了一个新的镍-铜合金的电子结构当铜含量范围在0≤a≤0.6时。它为(Ni)(3d↑)5 (3d↓)4(?)4+a + (Ni-Cu) 4S(?)(1-a)+a3+(Cu) (3d↑)5 (3d↓)5。当铜含量范围在0.6≤a≤1时,为(Ni-Cu)(3d↑)5(3d↓)5(4s)a。除了磁性以外,我们还对电子结构与镍-铜合金的其它理性质的关系进行了讨论。
In the magnetic study of nickel-copper alloys, it is found that the average atomic moment μ (Ni) (assuming that μ (Cu) = 0), which is averaged by the number of nickel atoms, has a linear relationship with the copper content aCu in the alloy. The average atomic moment of all atoms in an alloy does not have this linear relationship. After analyzing the electronic structure of various nickel-copper alloys in history, we propose a new electronic structure of nickel-copper alloy Copper content in the range of 0 ≤ a ≤ 0.6. (4) a + (Ni-Cu) 4S (?) (1-a) + a3 + (Cu) (3d ↑) 5 (3d ↓) 5. When the copper content in the range of 0.6 ≤ a ≤ 1, (Ni-Cu) (3d ↑) 5 (3d ↓) 5 (4s) a. In addition to magnetism, we also discuss the relationship between the electronic structure and other properties of nickel-copper alloys.
