| Outline of Final Research Achievements |
In an alloy, various internal freedoms such as atomic configuration, atomic displacement, magnetic spin configuration etc exist, and their excitations as well as evolution plays key roles for emerging various functional and structural properties. It is, however, quite a difficult task to describe an accurate free energy of a system with multiple internal freedoms. In the present studies, we developed efficient method based on (Continuous Displacement) Cluster Variation Method to convert internal freedom of alloys to configurational freedom of atomic species which is the central concern of conventional Cluster Variation Method. Among various results, finite temperature magnetism of fcc-Ni, order-order relaxation process associated with quenching operation on Ni3Al and displacive phase transition on a two-dimensional square lattice are emphasized.
