摘要

Integrating two-dimensional layered supercell (LSC) oxides and plasmonic Au nanostructures into one hybrid framework can open up multifunctionality tuning into a new level. In this work, Bi-based LSCs Bi₃Fe₂Mn₂O_x and Bi₂WO₆ incorporated with secondary plasmonic Au and/or ferromagnetic La_0.7Sr_0.3MnO₃ phases have been grown via pulsed laser deposition (PLD). Microstructural characterization results show the highly epitaxy film quality and distinct LSC structures despite the incorporated secondary phases. The nanocomposite films exhibit multiferroic and plasmonic responses due to the multi-phase coupling. This work provides a new approach of integrating self-assembled LSC-metal/oxide nanocomposite thin films for future multiferroics and spintronics device applications.
