Sm. Anlage et al., SURFACE IMPEDANCE MEASUREMENTS OF CUPRATE SUPERCONDUCTORS - ND1.85CE0.15CUO4-DELTA - A CASE-STUDY, Journal of superconductivity, 7(2), 1994, pp. 453-458
We present results on the temperature dependence of the surface impeda
nce of high-quality thin films and single crystals of the electron-dop
ed Nd1.85Ce0.15CuO4-delta cuprate superconductor. Surprisingly, these
measurements are consistent with the behavior of an s-wave BCS superco
nductor. We also briefly review some highlights of surface impedance m
easurements on hole-doped cuprate superconductors, and contrast those
with the results on Nd1.85Ce0.15CuO4-delta.
