• Note (General): The muon spin relaxation (?SR) method is a powerful tool to investigate the electronic state of Cu-based high-TC superconducting oxides. To reveal muon positions inside La2CuO4 gives us a useful information to achieve deeper understandings of the electronic states on its magnetically ordered state. However, any unified method to investigate muon positions have not yet been firmly established. For this reason, the ?SR results achieved on La2CuO4 in the early stage of high-TC history have not yet been fully explained. We are approaching this issue by using the density functional theory calculation method, with a supercell framework and including one muon as a dilute-charged impurity. The on-sites Coulomb potential, ?, is included to achieve correct electronic states of the La2CuO4. By considering the quantum local effects caused by the implanted muon and the Cu-spin states in the La2CuO4, we finally succeeded to reveal the muon positions that corresponds well with the ?SR experimental results. Adjusting the DFT and ?SR results, we also optimized ? to be 4.87(4) eV precisely, providing an accurate information of the electronic states in LCO and proposing a novel way to utilize ?SR experiment on many strongly correlated systems.; (主査) 客員教授 渡邊 功雄, 教授 網塚 浩, 教授 河本 充司; 理学院（物性物理学専攻）
