✦ Synopsis

Crystal potential of La2CuO4 for a positive muon is calculated by adding the atomic potentials of La, Cu and O atoms which are calculated by spin-dependent self-consistent atomic Shr6dinger equation. We have found that the stable site for a positive muon is located in the interlayer region between two Cu-O planes. Dipolar field and hyperfine field of Cu and O spin are calculated at the muon sites. The calculated result shows that the hyperfine field from spin-polarized apical oxygen does contribute to the local field at the muon site and that the contact interaction of a positive muon is sensitive to the muon site and 2p orbital of apical oxygen.
