The superconducting state in a single CuO2 layer:Experimental findings and scenario

TL;DR

This paper reviews experimental findings on single CuO2 layer superconductivity, challenging existing models by suggesting spin pairing via local exchange interactions as the underlying mechanism.

Contribution

It proposes a new scenario for superconductivity in single CuO2 layers based on experimental analysis, contrasting with prevalent theories.

Findings

No observable mixing of superconductivity and antiferromagnetism in layered structures

Superconductivity attributed to spin pairing via local exchange interactions

Experimental results challenge existing models of high-Tc cuprates

Abstract

The notable results shown by Bozovic et al. from measurements of synthesized one-unit-cell thick of La1.85Sr0.15CuO4,La2CuO4 HTS/AF/HTS tri-layer junctions query the predictions by prevalent models since there is no observable mixing of superconductivity and anti-ferromagnetism betwween the layers. In this article we make a brief survey of experimental results on the electronic structure of high-Tc cuprates and magnetic properties. Based on our analysis, we attribute superconductivity of a single CuO2 layer to spin pairing via local exchange interactions.
