摘要：
We have analyzed the temperature dependencies of the superfluid density in YBa2Cu3O7 along a- and b- crystallographic axes using the multicomponent order parameter for the superconducting gap. Estimated values of the gap components for the d-wave and the isotropic s-wave are Δd=29 meV and Δs=5 meV, correspondingly. Band structure parameters were taken accordingly ARPES and neutron scattering data.
