Nanoscale magnetophotonics

Abstract

This Perspective surveys the state-of-the-art and future prospects of science and technology employing the nanoconfined light (nanophotonics and nanoplasmonics) in combination with magnetism. We denote this field broadly as nanoscale magnetophotonics. We include a general introduction to the field and describe the emerging magneto-optical effects in magnetoplasmonic and magnetophotonic nanostructures supporting localized and propagating plasmons. Special attention is given to magnetoplasmonic crystals with transverse magnetization and the associated nanophotonic non-reciprocal effects, and to magneto-optical effects in periodic arrays of nanostructures. We give also an overview of the applications of these systems in biological and chemical sensing, as well as in light polarization and phase control. We further review the area of nonlinear magnetophotonics, the semiconductor spin-plasmonics, and the general principles and applications of opto-magnetism and nano-optical ultrafast control of magnetism and spintronics.

Active photonic platforms for the mid-infrared to the THz regime using spintronic structures

“…Another example is the case of Magneto Plasmonic (MP) systems, which combine MO and plasmonic materials, exploiting the synergy of their corresponding functionalities. In this sense, many approaches based on the plasmon enhanced MO activity of different MP nanostructures have been considered up to date, showing great potential in sensing and telecom applications in the visible and near-infrared (NIR) ranges [2][3][4][5][6]. Unfortunately, the MO activity of most materials is strongly reduced in the infrared (IR) and lower energies and, if the magnetic field action is desired to modulate nanophotonic platforms in this spectral range, a different magnetic mechanism is needed.…”

Microwave Magnon-Plasmon-Polaritons in the Ferromagnetic Metal–Screened Insulator Structure

“…The study of various SPP systems during the last 60 years has led to the appearance of a new branch of science and engineering such as plasmonics [5,[15][16][17][18][19][20][21]. Today, the study of the properties of SPPs is one of the main tasks of modern physics [18][19][20][21].…”

“…The study of various SPP systems during the last 60 years has led to the appearance of a new branch of science and engineering such as plasmonics [5,[15][16][17][18][19][20][21]. Today, the study of the properties of SPPs is one of the main tasks of modern physics [18][19][20][21]. It is so because, in particular, SPPs are highly promising from the viewpoint of their application in communication systems, medicine, and sensor devices, for measuring the electrophysical parameters of materials, developing the nanotechnology, and so on [5,[15][16][17][18][19][20][21].…”

“…At the same time, analogous studies of SPPs in magnetic media are either quite fragmentary or at the very beginning stage, although such systems are very interesting owing to the possibility to considerably change the properties of the SEMWs and SPPs at the interface between the media by means of magnetic fields. Among the interesting works in this area of plasmonics, it is ex-pedient to mention the study of SPPs in the structures with an artificial "left-handed" material [22,23], graphene/antiferromagnet heterostructures [24], on the surface of MgF 2 and FeF 2 antiferromagnets [25], in multilayer magnetic structures [21,26,27], layered metamaterials [28], and so forth. It is also necessary to mention work [29], where the spectrum of quasiparticles in a thin ferrite layer located on the metal surface was researched.…”

Single femtosecond laser pulse excitation of individual cobalt nanoparticles

“…The interaction of light and matter at the nanoscale is a topic of wide interest, with impact on applications ranging from optical manipulation of small objects to bioimaging and nanoplasmonics [1][2][3]. In recent years, a number of exciting new light-induced effects have been discovered in magnetism, which promise great potential for applications, for instance, in magnetic data storage, processing, or computation [4][5][6][7][8][9][10]. Of particular interest in this context is the exploitation of alloptical switching (AOS) effects, where ultrafast laser pulses allow one to control the spin state in individual building blocks in nanoscale magnetic devices [7,8,11].…”
