Magneto-Plasmonic Nanoparticles
César de Julián Fernández and Francesco Pineider
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.
5.1 Introduction
Magneto-plasmonics (MPs) is new concept of multifunctional nanomaterials
exhibiting simultaneously plasmonic and magnetic phenomena. MPs combine and
intertwine two separated materials science worlds, magnetism and photonics, at the
nanoscale. In general, MP materials are composed by the materials that originate
each phenomenon: plasmonic materials are elements constituted by mainly Au, Ag
and Cu while magnetic materials are formed by 3d metals and their oxides. Since
plasmonic phenomena mainly manifest in the nanometric range, also MP materials
are designed in this dimension range. At this scale, both plasmonics and magnetic
