Generation of magnonic spin wave traps
Frederik Busse, Maria Mansurova, Benjamin Lenk +2
Spatially resolved measurements of the magnetization dynamics induced by an intense laser pump-pulse reveal that the frequencies of resulting spin wave modes depend strongly on the…
Spin-wave modes and band structure of rectangular CoFeB antidot lattices
Benjamin Lenk, Nils Abeling, Jelena Panke +1
We present an investigation of rectangular antidot lattices in a CoFeB film. Magnonic band structures are numerically calculated, and band gaps are predicted which shift in frequen…
The building blocks of magnonics
Benjamin Lenk, Henning Ulrichs, Fabian Garbs +1
Novel material properties can be realized by designing waves' dispersion relations in artificial crystals. The crystal's structural length scales may range from nano- (light) up to…
Magnonic spin-wave modes in CoFeB antidot lattices
Henning Ulrichs, Benjamin Lenk, Markus Münzenberg
In this manuscript time-resolved magneto-optical Kerr effect experiments on structured CoFeB films are presented. The geometries considered are two dimensional square lattices of m…
Analytical expression of the magneto-optical Kerr effect and Brillouin light scattering intensity arising from dynamic magnetization
Jaroslav Hamrle, Jaromír Pištora, Burkard Hillebrands +2
Time-resolved magneto-optical Kerr effect (MOKE) and Brillouin light scattering (BLS) spectroscopy are important techniques for the investigation of magnetization dynamics. Within…
