摘要
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.
