Abstract

Engineering of emergent properties at oxide interfaces is an exciting route towards realizing oxide electronics. Such properties are often the result of a balance between cooperating and competing mechanisms in the materials, which are difficult to decouple. In this paper we address the interplay between antiferromagnetic spin axis and the occurrence of magnetic reconstructions at the (111)-oriented La_0.7Sr_0.3MnO₃/LaFeO₃ interface. We report a critical LaFeO₃ thickness where we observe a magnetic interface reconstruction with a net switchable Fe moment only for thicknesses less or equal to 16 d₁₁₁-layers of LaFeO₃. A change from out-of-plane to in-plane antiferromagnetic spin axis is found at the same critical thickness. We ascribe the interfacial moment to a successively decreased out-of-plane canting of the antiferromagnetic spin axis towards the in-plane La_0.7Sr_0.3MnO₃ magnetization at the interface. This points towards the importance of the local antiferromagnetic order interacting with concurrent structural reconstructions to establish a magnetically reconstructed interface.
