A new positive muon position in La₂CuO₄ is suggested from electronic and nuclear dipoles simulations. The muon site was found to be close to the center of a triangle plane of the CuO₆ octahedral that was formed by the apical and two in-plane oxygen. The magnetic moment of the Cu spin was estimated to be 0.66 μ_B/Cu in order to optimize the muon site. We also applied our method to the new vanadium compound, V₄S₉Br₄, in which four muon sites were observed in a magnetically ordered state.
