Project B07 brings together the fields of Magnonics and Plasmonics. The project investigates the emergent properties due to interactions between two collective excitations: plasmons (induced by optical near fields) and magnons. First, the influence of the magnetic field and the presence of a magnetic material on plasmonic excitations in metallic magneto-plasmonic heterostructures will be studied. Second, plasmon-magnon interactions will be realized by exploiting the possibility of surface plasmons to focus light at the nano-scale, and by engineering magnon spectra through nano-patterning techniques.

Aim 1: Manipulation of magneto-plasmon interaction: impact of magnetism on surface plasmons, i.e. manipulation of surface plasmon properties through the use of magnetic materials and external magnetic fields;

Aim 2: Demonstration und understanding of plasmon-magnon interaction: manipulation of magnon properties by using localized and propagating surface plasmons.
