Postdoc: Observation of THz magnons in space and time

European Magnetism Association EMA, Sweden

Updated: 4 days ago

Description of the offer :

We will follow the birth, propagation and death of magnon excitations in ferro- and antiferromagnetic materials at THz frequencies and on nm length scales using fs optical and free electron lasers. The main goal is to move from the commonly investigated long-wavelength magnons, dominated by magnetic dipolar coupling, to the short-wavelength, exchange dominated magnons (spin waves) that propagate with much larger speeds. We will explore the energy dissipation of such exchange dominated magnons in low-damping metallic and insulating materials to optimize energy efficiency of potential future magnonic devices. The postdoc should have a background in experimental condensed matter physics and experience with femtosecond optical lasers or x-ray facilities.
