Spin-wave frequency combs
Tobias Hula, Katrin Schultheiss, Francisco José Trindade Goncalves +11
We experimentally demonstrate the generation of spin-wave frequency combs based on the nonlinear interaction of propagating spin waves in a microstructured waveguide. By means of t…
Tunable Cooperativity in Coupled Spin--Cavity Systems
Lukas Liensberger, Franz X. Haslbeck, Andreas Bauer +5
We experimentally study the tunability of the cooperativity in coupled spin--cavity systems by changing the magnetic state of the spin system via an external control parameter. As…
Robust formation of nanoscale magnetic skyrmions in easy-plane thin film multilayers with low damping
Luis Flacke, Valentin Ahrens, Simon Mendisch +14
We experimentally demonstrate the formation of room-temperature skyrmions with radii of about 25\,nm in easy-plane anisotropy multilayers with interfacial Dzyaloshinskii-Moriya int…
Growth optimization of TaN for superconducting spintronics
Manuel Müller, Raphael Hoepfl, Lukas Liensberger +5
We have optimized the growth of superconducting TaN thin films on \ch{SiO2} substrates via dc magnetron sputtering and extract a maximum superconducting transition temperature of $…
High-throughput techniques for measuring the spin Hall effect
Markus Meinert, Björn Gliniors, Oliver Gueckstock +6
The spin Hall effect in heavy-metal thin films is routinely employed to convert charge currents into transverse spin currents and can be used to exert torque on adjacent ferromagne…
Temperature-dependent spin-transport and current-induced torques in superconductor/ferromagnet heterostructures
Manuel Müller, Lukas Liensberger, Luis Flacke +6
We investigate the injection of quasiparticle spin currents into a superconductor via spin pumping from an adjacent FM layer.To this end, we use NbN/\ch{Ni80Fe20}(Py)-heterostr…
Nonlinear losses in magnon transport due to four-magnon scattering
Tobias Hula, Katrin Schultheiss, Aleksandr Buzdakov +9
We report on the impact of nonlinear four-magnon scattering on magnon transport in microstructured Co25Fe75 waveguides with low magnetic damping. We determine the magnon propagatio…
Magnetoelasticity of thin films
Daniel Schwienbacher, Matthias Pernpeintner, Lukas Liensberger +6
We investigate the magnetoelastic properties of and thin films by measuring the mechanical properties of a dou…
Spin-wave propagation in metallic CoFe films determined by microfocused frequency-resolved magneto-optic Kerr effect
Lukas Liensberger, Luis Flacke, David Rogerson +3
We investigated the magnetization dynamics of a patterned CoFe-based heterostructure with a novel optical measurement technique that we call microfocused frequency-re…
High Spin-Wave Propagation Length Consistent with Low Damping in a Metallic Ferromagnet
Luis Flacke, Lukas Liensberger, Matthias Althammer +11
We report ultra-low intrinsic magnetic damping in CoFe heterostructures, reaching the low regime at room temperature. By using a broadband fer…
Exchange-enhanced Ultrastrong Magnon-Magnon Coupling in a Compensated Ferrimagnet
Lukas Liensberger, Akashdeep Kamra, Hannes Maier-Flaig +7
The ultrastrong coupling of (quasi-)particles has gained considerable attention due to its application potential and richness of the underlying physics. Coupling phenomena arising…
Spin transport in a magnetic insulator with zero effective damping
Tobias Wimmer, Matthias Althammer, Lukas Liensberger +5
Applications based on spin currents strongly profit from the control and reduction of their effective damping and their transport properties. We here experimentally observe magnon…
