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
Ondřej 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 Vojáček, Ondřej 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, Ondřej 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 Klíma, Ondřej Wojewoda, Jakub Krčma +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
Ondřej Wojewoda, Miela J. Gross, Jan Klíma +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…
