The anisotropy of the superfluid density in noncentrosymmetric CePt3Si

We report on the temperature dependence of the normalized superfluid density ρ in a single crystal of CePt3Si. The temperature response of ρs resembles that of polycrystalline samples; namely, the response is vigorously suppressed at high temperatures. The temperature behavior of the superfluid dens...

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