Abstract

The location of the positive muon used as a probe in highTc systems is investigated using the unrestricted Hartree-Fock cluster procedure. Our calculations indicate that μ+ is located in thea–c plane at a distance of 1.08 Å from the apical oxygen at a μ+-O(a)-Cu angle of 25°. The hyperfine field at this site is also calculated. Our results show the importance of including the local contact and dipolar contributions to the hyperfine field which arise from the unpaired electron spin distribution in the vicinity of the muon.
