Invited Speaker / Conférencier(ère) invité(e)

Magnetic polaritons have been known and observed for decades in ferromagnetic resonance spectroscopy experiments. A revival of interest and reinterpretation of these classical experiments, over the last decade, have focussed on the strong interaction between microwave photons and the collective spin excitations of ferromagnetic specimens in resonant cavities. Some of these studies have brought...

Magnetic structures are known to possess magnetic excitations confined to their surfaces and interfaces, but these spatially localized modes are often not resolved in spectroscopy experiments. We developed a theory to calculate the confined magnon spectra and its associated spin scattering function, which is the physical observable in spectroscopy based on neutron and electron scattering, and...
