“…In a recent work, we proved that the sensitivity of such a device could be enhanced by depositing a thin OAD TiO 2 layer onto the magneto-optical layer structure [474]. This transparent layer ensured a significant increase in the surface area available for adsorption, without affecting the optical signal coming from the device.…”

a b s t r a c tThe oblique angle configuration has emerged as an invaluable tool for the deposition of nanostructured thin films. This review develops an up to date description of its principles, including the atomistic mechanisms governing film growth and nanostructuration possibilities, as well as a comprehensive description of the applications benefiting from its incorporation in actual devices. In contrast with other reviews on the subject, the electron beam assisted evaporation technique is analyzed along with other methods operating at oblique angles, including, among others, magnetron sputtering and pulsed laser or ion beam-assisted deposition techniques. To account for the existing differences between deposition in vacuum or in the presence of a plasma, mechanistic simulations are critically revised, discussing well-established paradigms such as the tangent or cosine rules, and proposing new models that explain the growth of tilted porous nanostructures. In the second part, we present an extensive description of applications wherein oblique-angle-deposited thin films are of relevance. From there, we proceed by considering the requirements of a large number of functional devices in which these films are currently being utilized (e.g., solar cells, Li batteries, electrochromic glasses, biomaterials, sensors, etc.), and subsequently describe how and why these nanostructured materials meet with these needs.

“…[13] These two effects find application niches in, for example, sensing or telecommunications. [14,15,16,17,18,13] A magnetic field applied along the propagation direction of a circularly polarized light traveling in a chiral medium, does not modify the polarization state of the light and thus it induces no coupling between the eigenmodes of the chiral media. [19,20,21,22,23] Therefore, it is conceivable that plasmonic structures presenting simultaneously optical activity and magneto-optical properties are potential candidates to develop tuneable chiral structures whose properties could be controlled by a magnetic field.…”

In this work we analyse the magnetic field effects on the chirooptical properties of nm has a larger chirooptical response than the resonance at 650 nm, which, on the other hand, exhibits a larger magnetic field modulation of its chirooptical response.This dissimilar behaviour is due to the different physical origin of the chirooptical and magneto-optical responses. Whereas the chirooptical effects are due to the geometry of the structures, the magneto-optical response is related to the intensity of the electromagnetic field in the magnetic (Co) layers. We also show that the optical chirality can be modulated by the applied magnetic field, which suggests
