Abstract

The tetragonal c-axis alignment of Tc=23 K Pr1.85Ce0.15CuO3.97 superconducting powder was achieved in a 1 T alignment field with rotating powder/epoxy holder perpendicular to the alignment field. The in-plane penetration depth λab for this electron-doped superconductor was derived using zero-field-cooled Meissner diamagnetic data with low applied field (Ba<Habcl) parallel to the c-axis aligned powder. A small Pr paramagnetic contribution was subtracted. The temperature dependence of Δλab(T) = λab(T) - λab(0) [with λab(0) ∼ 133 nm] up to ∼0.5 Tc can be fitted well with a non-s-wave or d-wave-like power law Δλab(T) = AT2 + CT4, where the T2 law is dominated at low temperature. The present result agrees with recent phase-sensitive experiment, which indicates d-wave nature for these electron-doped 214 cuprates.
