本文研究了Fe-Pt、Co-Pt和Ni-Pt合金体系在有序相和无序相的电子和磁性。用线性Muffin-tin轨道方法研究了不同交换关联泛函对Fe-Pt、Co-Pt和Ni-Pt有序合金平衡晶格参数和磁矩的影响。在紧束缚线性化Muffin-tin轨道方法的框架下，采用增广空间递归方法对无序合金的电子结构进行了计算.短程有序的效果也被研究在这些系统的无序相。结果表明，与现有的实验值吻合良好。
We have studied the electronic and magnetic properties of Fe–Pt, Co–Pt and Ni–Pt alloy systems in ordered and disordered phases. The influence of various exchange–correlation functionals on the values of equilibrium lattice parameters and magnetic moments in ordered Fe–Pt, Co–Pt and Ni–Pt alloys have been studied using the linearized muffin-tin orbital method. The electronic structure calculations for the disordered alloys have been carried out using an augmented space recursion technique in the framework of the tight binding linearized muffin-tin orbital method. The effect of short-range order has also been studied in the disordered phase of these systems. The results show good agreement with available experimental values.
