Interplay of superconductivity and ferromagnetism in YBa₂Cu₃O₇<i>/</i> La_1−<i>x</i>Sr_<i>x</i>MnO₃ heterostructures

Abstract

Oxide manganite/cuprate superlattices are an attractive model system to study the proximity effect in oxide ferromagnet/cuprate superlattices. This report describes recent experimental results obtained on manganite/cuprate heterostructures. The experimental results are discussed in terms of the impact of hole charge transfer from cuprate to manganite layers on the proximity between the oxide ferromagnet and oxide superconductor layers.
