Ultrafast formation of a large dynamic magnetic soliton
OndÅej Wojewoda, Sina Mayr, Miela J. Gross +17
Nonlinear magnetization dynamics offers a rich variety of phenomena ranging from bistability to chaos. Here, we report the ultrafast formation of a dynamic magnetic soliton in thin…
Laterally Differentiated Polymorphs: a route to multifunctional nanostructures
Pete E. Lauer, Kensuke Hayashi, Yuichiro Kunai +10
Multifunctional materials can exhibit emergent behavior from the coupling of two or more different properties. For example, coupling between magnetic and ferroelectric order enable…
Polarization-resolved measurement of forward volume spin waves by micro-focused Brillouin light scattering
Krzysztof Szulc, Mengying Guo, OndÅej Wojewoda +7
We show how the micro-focused BLS signal of forward volume spin waves is formed and why it remains observable despite symmetry-based "suppression" expectations. A reciprocity-theor…
SpinWaveToolkit: Python package for (semi-)analytical calculations in the field of spin-wave physics
Jan KlÃma, OndÅej Wojewoda, Jakub KrÄma +4
We present an open-source Python package, SpinWaveToolkit (SWT), for (semi-)analytical modeling of spin-wave dynamics in thin ferromagnetic films and exchange-coupled magnetic bila…
Ultrafast propagation of magnon-polaritons
OndÅej Wojewoda, Miela J. Gross, Jan KlÃma +11
The manipulation of magnetization lies at the heart of spintronic and magnonic technologies, with the ultimate performance of such systems limited by the velocity at which magnetic…
