Andreev reflections from La2-xSrxCuO4 single crystals

  • 1. Tel Aviv Univ. (Israel)

Description

Andreev reflections have been studied at the interface between a gold tip and La2-xSrxCuO4 (x=0.11, 0.12) single crystals, along the (110) direction. The shape of the I(V) characteristic has been analyzed within the framework of the theory of Tanaka and Kashiwaya, allowing for an anisotropic order parameter. The data cannot be fitted either to a pure isotropic s-wave or pure d-wave symmetry. The best fit is obtained for an anisotropic gap, with Δmax = 15 meV and Δmin = 5 meV
