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…
Precise control of crystallography and magnetism in focused-ion-beam transformed iron-nickel thin films
Jakub Holobrádek, Libor VojáÄek, OndÅej Wojewoda +2
Focused ion beam irradiation of metastable FeNi thin films grown on Cu(100) substrates results in the localized transformation of the originally paramagnetic, face-ce…
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…
Mie-enhanced micro-focused Brillouin light scattering with wavevector resolution
Jakub KrÄma, OndÅej Wojewoda, Martin HrtoÅ +4
Magnons, the quanta of spin waves, are magnetic excitations of matter spanning through the entire crystal's Brillouin zone and covering a wide range of frequencies ranging from sub…
