MA 19.92: Poster

Tuesday, March 15, 2011, 10:45–13:00, P2

Scanning Kerr Microscopy - Spinwave Propagation in Ferromagnetic Nanostructures — •Kim Martens, Sebastian Mansfeld, Felix Balhorn, Jesco Topp, Wolfgang Hansen, Detlef Heitmann, and Stefan Mendach — Institute for Applied Physics, University of Hamburg, Germany

We use a scanning Kerr microscope for the time resolved mapping of spin waves in thin Permalloy films. In my poster I will introduce the concept and functionality of time resolved scanning Kerr microscopy. Additionally, I will present our recent experiments on spin-wave propagation and damping in patterned permalloy films.
