Abstract

We have analyzed the possible temperature variation of the penetration depth λ(T) in the (d+s)-wave superconductivity model of hybrid pairing, which accounts for the high Tc cuprates with an orthorhombic distortion. The slope of the Δλ(T)∝T for TTc and its dependence on the Δs/Δd admixture in the gap function is analyzed quantitatively. The impurity scattering is taken into account. Recent measurements of the penetration depth in YBa2Cu3O6.95 single crystals are discussed in terms of this model.
