Nodeless superconductivity in the infinite-layer electron-doped cuprate superconductor Sr0.9La0.1CuO2


Khasanov, R; Shengelaya, A; Maisuradze, A; Di Castro, D; Savic, I M; Weyeneth, S; Park, M S; Jang, D J; Lee, S I; Keller, H (2008). Nodeless superconductivity in the infinite-layer electron-doped cuprate superconductor Sr0.9La0.1CuO2. Physical Review B, 77(18):184512-6pp.

Abstract

We report on measurements of the in-plane magnetic penetration depth lambdaab in the infinite-layer electron-doped high-temperature cuprate superconductor Sr0.9La0.1CuO2 by means of muon-spin rotation. The observed temperature and magnetic field dependences of lambdaab are consistent with the presence of a substantial s-wave component in the superconducting order parameter, in good agreement with the results of tunneling, specific heat, and small-angle neutron scattering experiments
