Two-magnon scattering in the framework of the Lippmann-Schwinger equation
Jorge Marquez Chavez, OndÅej Wojewoda, Yixuan Song +2
The paper presents a Lippmann‑Schwinger formalism to describe two‑magnon scattering from weak defects, linking the overlap of effective‑field perturbations with degenerate spin‑wav…
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…
1D YIG hole-based magnonic nanocrystal
K. O. Levchenko, K. DavÃdková, R. O. Serha +12
Magnetic media with artificial periodic modulation-magnonic crystals (MCs) - enable tunable spin-wave dynamics and band structure engineering. Nanoscaling enhances these capabiliti…
Modeling of the micro-focused Brillouin light scattering spectra
OndÅej Wojewoda, Martin HrtoÅ, Michal Urbánek
Although micro-focused Brillouin light scattering (BLS) has been used for more than twenty years, it lacks a complete theoretical description. This complicates the analysis of expe…
