In a single tight binding band with modest effective mass anisotropy, the resulting superconducting gap, in the nearly antiferromagnetic Fermi liquid, has a main component exhibiting dx2−y2symmetry but also has a minor extended s‐wave contribution (including a constant part). This leads to anisotropy in the in plane penetration depth as is measured and can explain the recent observation of a DC Josephson current between Pb and YBa2Cu3O7−&dgr;.
