Magnetoplasmonics: current challenges and future opportunities

Abstract

Plasmonics represents a unique approach to confine and enhance electromagnetic radiation well below the diffraction limit, bringing a huge potential for novel applications, for instance in energy harvesting, optoelectronics, and nanoscale biochemistry. To achieve novel functionalities, the combination of plasmonic properties with other material functions has become increasingly attractive. In this Perspective, we review the current state of the art, challenges, and future opportunities in nanoscale magnetoplasmonics, an emerging area aiming to merge magnetism and plasmonics in confined geometries to control either plasmons, electromagnetic-induced collective electronic excitations, using magnetic properties, or magnetic phenomena with plasmons. We begin by highlighting the cornerstones of the history and principles of this research field. We then provide our vision of its future development by showcasing raising research directions in mid-infrared light-driven spintronics and novel materials for magnetoplasmonics, such as transparent conductive oxides and hyperbolic metamaterials. As well, we provide an overview of recent developments in plasmon-driven magnetization dynamics, nanoscale optomagnetism and acousto-magnetoplasmonics. We conclude by giving our personal vision of the future of this thriving research field.
