Abstract

Interfacial phenomena in perovskite oxide superlattices have the potential to provide unique functional properties for a diverse range of applications, including sensing, energy conversion, and information technology. The example of antiferromagnetic/ferromagnetic superlattices composed of La0.7Sr0.3FeO3 (LSFO) and La0.7Sr0.3MnO3 (LSMO) sublayers is discussed in detail. In this system, the antiferromagnetic order parameter in LSFO and the ferromagnetic order parameter in LSMO display dissimilar dependences on sublayer thickness and temperature due to the competition between different magnetic interactions. For a small range of sublayer thicknesses, a robust spin-flop coupling is observed such that the alignment of the LSMO magnetization with a magnetic field leads to the reorientation of the Fe moments in the LSFO layer to maintain a perpendicular orientation between the Fe and Mn moments.
