Strong-coupling BCS superconductivity in noncentrosymmetric BaPtSi sub(3): a low-temperature study

We report on measurements of the temperature dependence of the magnetic penetration depth of a high-quality sample of BaPtSi sub(3) (T sub(c) = 2.25 K). We observe a temperature-independent behaviour below T [Asymptotically = to] 0.2 T sub(c), which is firm evidence for the presence of an isotropic...

description We report on measurements of the temperature dependence of the magnetic penetration depth of a high-quality sample of BaPtSi sub(3) (T sub(c) = 2.25 K). We observe a temperature-independent behaviour below T [Asymptotically = to] 0.2 T sub(c), which is firm evidence for the presence of an isotropic superconducting gap in this material. In the whole temperature range the superfluid density is described well by a strong-coupling Bardeen-Cooper-Schrieffer (BCS) model with an isotropic gap Delta sub(0) [asymptotically =] 2k sub(B)T sub(c). Our results provide further support for conventional BCS superconductivity in the nonmagnetic members of the noncentrosymmetric family of superconductors that crystallize with the BaNiSn sub(3)-type tetragonal structure.
