Nonreciprocal Spin Waves in Nanoscale Domain Walls Detected by Scanning X-ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers
Ping Che, Axel Deenen, Andrea Mucchietto +10
Spin wave nonreciprocity in domain walls (DWs) allows for unidirectional signal processing in reconfigurable magnonic circuits. Using scanning transmission x-ray microscopy (STXM),…
Generation and annihilation of skyrmions and antiskyrmions in magnetic heterostructures
Sabri Koraltan, Claas Abert, Florian Bruckner +3
We demonstrate the controlled generation and annihilation of (anti)skyrmions with tunable chirality in magnetic heterostructures by means of micromagnetic simulations. By making us…
Symmetry of the Magnetoelastic Interaction of Rayleigh and Shear Horizontal Magnetoacoustic Waves in Nickel Thin Films on LiTaO
M. Küß, M. Heigl, L. Flacke +5
We study the interaction of Rayleigh and shear horizontal surface acoustic waves (SAWs) with spin waves in thin Ni films on a piezoelectric LiTaO substrate, which supports both…
Ultrafast high-harmonic nanoscopy of magnetization dynamics
Sergey Zayko, Ofer Kfir, Michael Heigl +4
Light-induced magnetization changes, such as all-optical switching, skyrmion nucleation, and intersite spin transfer, unfold on temporal and spatial scales down to femtoseconds and…
Dipolar-stabilized first and second-order antiskyrmions in ferrimagnetic multilayers
Michael Heigl, Sabri Koraltan, Marek Vaňatka +13
Skyrmions and antiskyrmions are topologically protected spin structures with opposite topological charge. Particularly in coexisting phases, these two types of magnetic quasi-parti…
Microscopic origin of magnetization reversal in exchange-coupled ferro-/ferrimagnetic bilayers
Michael Heigl, Christoph Vogler, Andrada-Oana Mandru +4
In this study, the magnetic reversal process of exchange-coupled bilayer systems, consisting of a ferrimagnetic TbFeCo alloy layer and a ferromagnetic [Co/Ni/Pt]N multilayer, was i…
Hysteresis-free magnetization reversal of exchange-coupled bilayers with finite magnetic anisotropy
Christoph Vogler, Michael Heigl, Andrada-Oana Mandru +5
Exchange-coupled structures consisting of ferromagnetic and ferrimagnetic layers become technologically more and more important. We show experimentally the occurrence of completely…
Nonreciprocal Dzyaloshinskii-Moriya magnetoacoustic waves
Matthias Küß, Michael Heigl, Luis Flacke +4
We study the interaction of surface acoustic waves with spin waves in ultra-thin CoFeB/Pt bilayers. Due to the interfacial Dzyaloshinskii-Moriya interaction (DMI), the spin wave di…
Magnetic properties of Co/Ni-based multilayers with Pd and Pt insertion layers
Michael Heigl, Ralph Wendler, Simon Haugg +1
In this study, the influence of Pd and Pt insertion layers in Co/Ni multilayers (MLs) on their magnetic properties, e.g. magnetic anisotropies, saturation magnetization, coercivity…
Dynamic Acoustic Control of Individual Optically Active Quantum Dot-like Emission Centers in Heterostructure Nanowires
Matthias Weiß, Jörg B. Kinzel, Florian J. R. Schülein +10
We probe and control the optical properties of emission centers forming in radial het- erostructure GaAs-Al0.3Ga0.7As nanowires and show that these emitters, located in Al0.3Ga0.7A…
Radio frequency occupancy state control of a single nanowire quantum dot
Matthias Weiß, Florian J. R. Schülein, Jörg B. Kinzel +8
The excitonic occupancy state of a single, nanowire-based, heterostructure quantum dot is dynamically programmed by a surface acoustic wave. The quantum dot is formed by an interfa…
