摘要：

We calculate the electron spin susceptibility for the superconducting state of YBa2Cu3O7 using a band structure with nearest- and next-nearest-neighbor hopping, a momentum-dependent spin-spin interaction, and a superconducting pp with d(x2-y2) Symmetry. Our calculated nuclear magnetic relaxation rates and Knight shift agree favorably with experiment. Our work provides further evidence for a d(x2-y2) pairing state and demonstrates that antiferromagnetic correlations persist in the superconducting state.
