Description |
We identify a distinct superconducting phase at the interface of a La1.48Nd0.4Sr0.12CuO4/La1.84Sr0.16CuO4 epitaxial bilayer system using ac screening measurements. A model based on interdiffusion of quasiparticles and condensate at the interface yields a thickness of ∼25 nm for the interfacial layer. Two-dimensional superconductivity of the interface layer appears to be governed by Kosterlitz-Thouless-Berezinskii transition. A parallel magnetic field suppresses the superconducting transition temperature of this layer with a pair-breaking parameter α varying as H2.
