AbstractThe main objective of the thesis is to study the phenomenology associated to nanostructures possessing surface plasmons and magneto-optical activity, the so-called magnetoplasmonic structures. These structures will be applicable in a broad spectrum of research and industrial areas. In particular, they are important elements in addressing tunability capabilities in plasmon-based nano-optical device. Also a new branch of biosensors with enhanced sensitivity are based on magneto-optical modulation. The magneto-plasmonic materials studied along this thesis offer the unique ability to control their properties in more than one way, since the magneto-optical response will be dramatically affected by the excitation of a plasmon, but also, their optical response can be actively tuned by means of an external agent: a magnetic field. We will mainly concentrate on the first aspect, where the different materials and structures considered will lead to the enhancement of the magneto-optical response due to the modifications of the electromagnetic field induced by plasmon resonances. In what follows, we will briefly describe the surface plasmon polaritons , pointing out their main characteristics. Since we are going to mainly analyze the magneto-optical response, we will devote Chapter 2 to describe in detail the different magneto-optical configurations and experimental setups.
