Coupled spin dynamics in epitaxial trilayer heterostructures of ferrimagnetic garnet
A. Del Giacco, M. J. Gross, O. Wojewoda +9
The magnetization dynamics of an all-garnet trilayer consisting of Y3Fe5O12/Y3Fe3Al2O12/Y3Fe5O12 (YIG/YIAG/YIG) is analysed. The two magnetic YIG layers, separated by a 4 nm thick…
Ultrafast formation of a large dynamic magnetic soliton
Ondřej 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…
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…
