Query: Magnetophotonics for sensing and magnetometry towards industrial
  applications   Magnetic nanostructures sustaining different kinds of optical modes have been
used for magnetometry and label-free ultrasensitive refractive index probing,
where the main challenge is the realization of compact devices able to transfer
this technology from research laboratories to smart industry. This Perspective
discusses the state-of-the-art and emerging trends in realizing innovative
sensors containing new architectures and materials exploiting the unique
ability to actively manipulate their optical properties using an externally
applied magnetic field. In addition to the well-established use of propagating
and localized plasmonic fields, in the so-called magnetoplasmonics, we
identified a new potential of the all-dielectric platforms for sensing to
overcome losses inherent to metallic components. In describing recent advances,
emphasis is placed on several feasible industrial applications, trying to give
our vision on the future of this promising field of research merging optics,
magnetism, and nanotechnology.
