Coherence and dissipation of spin-wave eigen modes in magnetic micro- and nano-structures

• Applicant: Professor Dr. Burkard Hillebrands
• Subject Area: Experimental Condensed Matter Physics
• Term: from 2002 to 2009
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5374487

Subject is the spatio-temporal dynamics in lithographically prepared sub-micrometer magnetic islands with domains. Using the Brillouin light scattering technique the spin wave eigenmode spectrum is investigated as a function of the domain structure. The utilization of Brillouin light scattering in the "Fourier microscope" mode allows the determination of the spatial distribution of the spin wave mode intensities and it provides access to spin wave localization effects in individual domains. A second subject is the dynamic coupling between magnetic islands for small island separations.
