Title: Magnetic field dependence of high- T c interface superconductivity in L a 1.55 S r 0.45 Cu O 4 / L a 2 Cu O 4 heterostructures

Abstract

Heterostructures made of a layer of a cuprate insulator La 2CuO 4 on the top of a layer of a nonsuperconducting cuprate metal La 1.55Sr 0.45CuO 4 show high-T c interface superconductivity confined within a single CuO 2 plane. Given this extreme quasi-two-dimensional quantum confinement, it is of interest to find out how interface superconductivity behaves when exposed to an external magnetic field. With this motivation, we have performed contactless tunnel-diode-oscillator-based measurements in pulsed magnetic fields up to 56 T as well as measurements of the complex mutual inductance between a spiral coil and the film in static fields up to 3 T. Remarkably, we observe that interface superconductivity survives up to very high perpendicular fields, in excess of 40 T. Additionally, the critical magnetic field H m(T) reveals an upward divergence with decreasing temperature, in line with vortex melting as in bulk superconducting cuprates.
