Recent advances in magnonics
Dirk Grundler, Benedetta Flebus
Magnonics is an exciting and rapidly growing field revolving around the study and manipulation of magnons, the low-lying collective excitations of magnetically ordered systems. This field has emerged in response to both fundamental physics interests and th ...
2023Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Raw data associated to the manuscript ‘’Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies‘’, Physical Review Materials 7, 054407(2023); doi: 10.1103/PhysRevMaterials.7.054407 Information about file fo ...
Zenodo2023Spin wave dispersion of ultra-low damping hematite ( α−Fe2O3 ) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and wave-based computation at GHz frequencies focused on the artificial ferrimag ...
2023Atomic layer deposition of Ni and Ni80Fe20 for tubular spin-wave nanocavities
Magnetic thin films and magnetic nanostructures have become essential components of modern technological applications. Modern branches of magnetisms focus on spin-charge coupling (spintronics) and the collective excitation of spin waves in magnetically ord ...
EPFL2021Magnonic crystals with reconfigurable magnetic defects for spin-based microwave electronics
Collective spin excitations can propagate in magnetically ordered materials in the form of waves. These so-called spin waves (SWs) or magnons are promising for low-power beyond-CMOS information processing, which does not rely anymore on the lossy movement ...
EPFL2021Direct observation of multiband transport in magnonic Penrose quasicrystals via broadband and phase-resolved spectroscopy
Dirk Grundler, Sho Watanabe, Mohammad Hamdi, Vinayak Shantaram Bhat
Quasicrystals are aperiodically ordered structures with unconventional rotational symmetry. Their peculiar features have been explored in photonics to engineer bandgaps for light waves. Magnons (spin waves) are collective spin excitations in magnetically o ...
2021Static and dynamic properties of non-collinear quantum antiferromagnets explored by neutron scattering
This thesis is devoted to the investigation of static and dynamic properties of
two different sets of quantum magnets with neutron scattering techniques and
the help of linear spin wave theory.
Both systems are copper-based with spin-1/2, which makes them ...
EPFL2021Angular Momentum in Rotating Superfluid Droplets
Christoph Bostedt, Camila Bacellar Cases Da Silveira
The angular momentum of rotating superfluid droplets originates from quantized vortices and capillary waves, the interplay between which remains to be uncovered. Here, the rotation of isolated submicrometer superfluid He-4 droplets is studied by ultrafast ...
AMER PHYSICAL SOC2020h/e oscillations in interlayer transport of delafossites
Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke
Microstructures can be carefully designed to reveal the quantum phase of the wave-like nature of electrons in a metal. Here, we report phase-coherent oscillations of out-of-plane magnetoresistance in the layered delafossites PdCoO2 and PtCoO2. The oscillat ...
2020Single shot acquisition of spatially resolved spin wave dispersion relations using X-ray microscopy
For understanding magnonic materials the fundamental characterization of their frequency response is essential. However, determining full dispersion relations and real space wavelength measurements are challenging and time-consuming tasks. We present an ap ...
