TLDR
Magnetoplasmonic nanoparticles encompass in a single nano-entity all the rich science and promising applications of the plasmonics and magnetic nanoworlds as discussed by the authors, and they are excellent benchmark materials to develop and investigate multiresponsive multifunctional nanosystems that now are required in an increasing number of technologies, such as biomedicine, pharmacy, catalysis, optoelectronics and data storage.
Abstract
Magnetoplasmonics nanoparticles encompass in a single nano-entity all the rich science and promising applications of the plasmonics and magnetic nanoworlds. The difficult liaison and a certain incompatibility between plasmonics and magnetic phenomena, due to the different chemical-physical origins and supporting materials, are overcome thanks to the design and synthesis of novel nanostructures. The variations of properties, interactions and synergies of both phenomena and materials demonstrate how rich and surprising the matter is at nanoscale and the promising applications. In fact, we show how not only light and magnetism can interplay but also other phenomena like forces, heat, electric field and chemical interactions, between others, can show synergism. Magnetoplasmonic systems are excellent benchmark materials to develop and investigate multi-responsive multifunctional nanosystems that now are required in an increasing number of technologies, such as biomedicine, pharmacy, catalysis, optoelectronics and data storage.

Impact of Core Dielectric Properties on the Localized Surface Plasmonic Spectra of Gold-Coated Magnetic Core–Shell Nanoparticles B

TL;DR: Extended Mie theory for multilayer particles is used to examine the individual effects of the real and imaginary components of core refractive indices on Au-shell NP plasmonic peaks and shows that the addition of a nonabsorbing polymer layer to the core surface decreases the dampening of the cavity plAsmon and increases LSPR spectral intensity.

Extinction by a spherical particle in an absorbing medium

TL;DR: In this article, the extinction cross section for an arbitrary spherical particle that is embedded in an absorbing medium is derived by considering that which is measured in an actual extinction experiment, and the resultant "optical theorem" is similar in form to the optical theorem for particles in a nonabsorbing medium.

Effects of dielectric screening on the optical properties of metallic nanoshells

TL;DR: In this article, the authors extended the time dependent density functional method for the calculation of optical properties of metallic nanoshells to include the combined influence of a dielectric core and a Dielectric embedding medium, and the coupling between the polarization charges at the inner and outer surfaces of the shell was found to strongly influence the position of the plasmon resonances.
