At the interface between nanophotonics (optics at nanometer scales) and magnetism, this master and PhD project consists in using metallic nanostructures, known as optical nanoantennas, to generate strong and confined stationary magnetic fields. At first, the successful candidate will characterise the created magnetic field using a magnetic force microscope (MFM) present in our lab. From there, more in-depth studies will follow during the course of a PhD project, involving ultra-fast optics, magnetic trapping and magneto- luminescence sensing. Collaborations with external groups are expected; students with appetence in traveling are encouraged.
