Abstract

We report on the temperature dependence of the normalized superfluid density ρ in a single crystal of CePt₃Si. The temperature response of ρ_s resembles that of polycrystalline samples; namely, the response is vigorously suppressed at high temperatures. The temperature behavior of the superfluid density anisotropy (ρ_c/ρ_ab) is nonmonotonic, in agreement with theoretical predictions.
