Reciprocal Space Approach to Dipolarly Coupled Magnetic Hetero-Structures
A. Del Giacco, L. Menna, M. J. Gross +7
We present an analytical framework capable of describing spin-waves dynamic in magnetic hetero-structures composed of a pair of exchange-decoupled magnetic layers separated by a no…
Sculpting Spin-Wave Landscapes via Curvature of 2D Magnonic Crystals
OndÅej Wojewoda, Robert Kraft, Olha Bezsmertna +11
Engineering the dispersion relation is one of the key ingredients enabling the application of spin waves in computational elements. One way to engineer the spin-wave band structure…
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…
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…
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…
