Outline of Final Research Achievements |
Simulating magnetic properties is an important technique for understanding the basic properties of materials; however, the simulation is extremely difficult for polynuclear T-term complexes, possessing a lot of T-term magnetic centers. In this study, a purpose is to conduct magnetic simulations for polynuclear T-term complexes. All the secular matrices were solved for the T-term magnetic centers, and the theoretical equations were derived for the polynuclear T-term complexes. As a result, difficult magnetic properties were successfully simulated for polynuclear T-term complexes.

Academic Significance and Societal Importance of the Research Achievements |
磁性シミュレーションは、スピントロニクスとも関連した重要な技術の一つであるが、T項多核錯体ではシミュレーションは困難を極める。本研究では、一つのT項磁気中心について、行列方程式を文字式の形で解き、これを組み合わせることでT項多核錯体用の磁性理論式を導出した点が特徴である。この方法によって大幅な計算コストの節約ができ、これまで不可能であったT項一次元ポリマーやT項二次元ポリマーの磁気シミュレーションに成功した点に学術的意義がある。
