Surface magnetoplasmons in semiconductors

Physical Review B, 1978
This comment is intended to complete the picture of dispersion curves for surface polaritons for $n$-InSb with ${\stackrel{\ensuremath{\rightarrow}}{\mathrm{B}}}_{0}$ parallel to the surface and $\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}}\ensuremath{\parallel}{\stackrel{\ensuremath{\rightarrow}}{\mathrm{B}}}_{0}$ as given by Wallis, Brion ...

On the observation of surface magnetoplasmons

Optics Communications, 1973
Abstract It is shown that, of the two techniques (grating or prism coupling) proposed for the observation of surface magnetoplasmons, the prism technique appears far superior. An analytic reflectivity formula is presented which will be necessary in the analysis of surface magnetoplasmon experimental data.

Magnetoplasmonics in Au-Nanostructures

Materials Today: Proceedings, 2021
Abstract Plasmonics of Au nanostructures are studied theoretically using Mie’s formalism in the presence of static external magnetic field. Optical constants such as extinction coefficient is found to be dependent on external environment of Au nanoparticles. Absorption spectrum depends on strength of static external magnetic field.

Magnetoplasmon excitations in Graphene

Physica E: Low-dimensional Systems and Nanostructures, 2008
Abstract In the frame of the Hartree–Fock approximation, the dispersion of magnetoplasmons in Graphene is derived for transitions implying the n = 0 Landau Level and those corresponding to the electron–hole transitions. It is shown that the electron–electron interactions lead to a strong re-normalization of the apparent Fermi velocity of ...

Circular Magnetoplasmonic Modes in Gold Nanoparticles

Nano Letters, 2013
The quest for efficient ways of modulating localized surface plasmon resonance is one of the frontiers in current research in plasmonics; the use of a magnetic field as a source of modulation is among the most promising candidates for active plasmonics. Here we report the observation of magnetoplasmonic modes on colloidal gold nanoparticles detected by

Magnetoplasmons and the repeated magnetoroton spectrum

Physical Review B, 1988
The excitation energies of the noninteracting two-dimensional electron gas in a strong perpendicular magnetic field are multiples of \ensuremath{\Elzxh}${\ensuremath{\omega}}_{c}$. We show that in the presence of interactions there are inter-Landau-level excitation modes which exactly repeat the intra-Landau-level spectrum when shifted by \ensuremath ...

Magnetoplasmons of the two-dimensional electron grid

Physical Review Letters, 1993
We present a theory of the magnetoplasmons of two-dimensional electron grid (antidot) structures. We develop a variational Wigner-Seitz model to study such periodic electron structures. We derive an analytical solution for the far-infrared (FIR) response, and obtain results in quantitative agreement with experiments.

Multifunctional Magnetoplasmonic Nanomaterials and Their Biomedical Applications

Journal of Biomedical Nanotechnology, 2014
Multifunctional magnetoplasmonic (Au-Fe(x)O(y)) nanomaterials are characterized by some features of iron oxide and gold, such as surface chemistry, special optical properties, and superparamagnetic properties, which have helped to draw much attention to their biomedical applications. In this review, the state of the art of this rapidly developing field

Resonant surface magnetoplasmons in two-dimensional magnetoplasmonic crystals excited in Faraday configuration

Journal of Applied Physics, 2012
The resonant excitation of surface magnetoplasmons in Faraday configuration is studied via spectroscopy of the longitudinal magneto-optical Kerr effect (LKE) in two-dimensional nickel-based magnetoplasmonic crystals. The fulfillment of phase matching conditions for surface plasmon-polaritons using both reciprocal vectors of the magnetoplasmonic crystal
