摘要：
We present a muon-spin rotation study of the optimally doped cuprate superconductor (BiPb)(2)(SrLa)(2) CuO6+delta . The measured magnetic field dependence of the in-plane magnetic penetration lambda (ab) suggests superconductivity with a dominant d-wave order parameter. The comparison of the temperature dependence of lambda (ab) with calculations, assuming the angular gap symmetry as obtained from photoemission measurements, is consistent with a partial suppression of the quasi-particle weight towards the anti-nodal region of the Fermi surface. This suggests that the superconducting and the pseudogap state are dominated by different parts of the Fermi surface.
