Surface Plasmon Resonance (SPR) sensors are widely used for different applications and the main task in this sphere is increasing of the sensitivity. One of the ways – is adding an additional type of modulation, for example, by magnetic field. Typical SPR sensors consists of noble metal/dielectric materials and appreciable modulation can be reached in magnetic fields up to several tesla. The other way is using magneto-optical (MO) effects. It is possible to combine both of these ways by using the magnetoplasmonic crystals (MPlCs) – multilayer structures fabricated of noble and ferromagnetic layers on substrate with certain spatial profile. This way can demonstrate that it is possible both to enhance the MO activity of the system by surface plasmon excitation, and to modulate the surface plasmon properties by application the external magnetic field. Applications can be related to high sensitivity and spatial resolution of such type of sensor. Possibility of scanning the surface of MPlCs with focused light beam opens a possibility of performing high-precision mapping of stray fields, which can be useful for fundamental science or medical applications.
