摘要: We propose a weakly coupled two-band model with d(x)(2)-y(2) pairing symmetry to account for the anomalous temperature dependence of superfluid density rho(s) in electron-doped cuprate superconductors. This gives unified explanation presence an upward curvature near T-c and weak low temperatures. Our work resolves discrepancy interpretation different experimental measurements suggests that cuprates has predominately whole doping range.
