The anisotropy of the superfluid density in noncentrosymmetric CePt3Si

Abstract:

We report on the temperature dependence of the normalized superfluid density ρ in a single crystal of CePt<inf>3</inf>Si. The temperature response of ρ<inf>s</inf> resembles that of polycrystalline samples; namely, the response is vigorously suppressed at high temperatures. The temperature behavior of the superfluid density anisotropy (ρ<inf>c</inf>/ρ<inf>ab</inf>) is nonmonotonic, in agreement with theoretical predictions. © 2007 Elsevier B.V. All rights reserved.
