A Topological Spin on Racetrack Memory
Benjamin Zingsem
Magnetic racetrack memory requires localized carriers that combine rapid motion, resistance to perturbations and a detectable signal. Here we show how a 360° domain wall in a hollo…
Influence of amorphous phase on coercivity in SmCo5-Cu nanocomposites
Franziska Staab, Yangyiwei Yang, Eren Foya +10
Severe plastic deformation of powder blends consisting of SmCo5-Cu results in magnetically hardened nanocomposite bulk materials. The microstructure is continuously refined with in…
Emergence of net magnetization by magnetic-field-biased diffusion in antiferromagnetic L1 NiMn
Nicolas Josten, Olga Miroshkina, Sakia Noorzayee +6
NiMn is a collinear antiferromagnet with high magneto crystalline anisotropy (). Through magnetic annealing of NiMn with excess Ni, strongly pi…
Imaging non-standing spin-waves in confined micron-sized ferromagnetic structures under uniform excitation
Santa Pile, Thomas Feggeler, Taddäus Schaffers +10
A non-standing character of directly imaged spin-waves in confined micron-sized ultrathin permalloy (Ni\textsubscript{80}Fe\textsubscript{20}) structures is reported along with evi…
Element-specific visualization of dynamic magnetic coupling in a Co/Py bilayer microstructure
Thomas Feggeler, Ralf Meckenstock, Detlef Spoddig +8
We present the element-specific and time resolved visualization of uniform ferromagnetic resonance excitations of a Permalloy (Py) disk - Cobalt (Co) stripe bilayer microstructure.…
Unidirectional anisotropy in cubic FeGe with antisymmetric spin-spin-coupling
Nicolas Josten, Thomas Feggeler, Detlef Spoddig +8
We report strong unidirectional anisotropy in bulk polycrystalline B20 FeGe measured by ferromagnetic resonance spectroscopy. Bulk and micron-sized samples were produced and analyt…
