Abstract

The tetragonal c-axis alignment of T_c=23 K Pr_1.85Ce_0.15CuO_3.97 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 λ_ab for this electron-doped superconductor was derived using zero-field-cooled Meissner diamagnetic data with low applied field (B_a<H^ab_cl) parallel to the c-axis aligned powder. A small Pr paramagnetic contribution was subtracted. The temperature dependence of Δλ_ab(T) = λ_ab(T) - λ_ab(0) [with λ_ab(0) ∼ 133 nm] up to ∼0.5 T_c can be fitted well with a non-s-wave or d-wave-like power law Δλ_ab(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.
