A Topological Spin on Racetrack Memory: Stability and Transport of 360° Domain Walls in Magnetic Nanotubes
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…
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…
Specific Heat of Spin Excitations Measured by FerromagneticResonance
Benjamin W. Zingsem, Michael Winklhofer, Sabrina Masur +4
Using ferromagnetic-resonance spectroscopy (FMR), we investigate the anisotropic properties of epitaxial 3 nmPt/2 nmAg/10 nmFe/10 nmAg/GaAs(001) films in fully saturated meta-stabl…
Enhanced and Tunable Spin-Orbit Coupling in Tetragonally Strained Fe-Co-B Films
Ruslan Salikhov, Ludwig Reichel, Benjamin Zingsem +8
We have synthesized 20 nm thick films of tetragonally strained interstitial Fe-Co-B alloys epitaxially grown on Au55Cu45 buffer layer. The strained axis is perpendicular to the fil…
