We report on the controlled switching of domain wall (DW) magnetization in aligned stripe domain structures, stabilized in [Co (0.44 nm)/Pt (0.7 nm)] (, 100, 150) multi…
Atomic Layer Deposition of Yttrium Iron Garnet Thin Films for 3D Magnetic Structures
M. Lammel, D. Scheffler, D. Pohl +11
A wide variety of new phenomena such as novel magnetization configurations have been predicted to occur in three dimensional magnetic nanostructures. However, the fabrication of su…
Unveiling the three-dimensional spin texture of skyrmion tubes
Daniel Wolf, Sebastian Schneider, Ulrich K. Rößler +6
Magnetic skyrmions are stable topological solitons with complex non-coplanar spin structures. Their nanoscopic size and the low electric currents required to initiate and control t…
Non-local magnon-based transport in yttrium iron garnet/platinum heterostructures at high temperatures

The spin Hall effect in a heavy metal thin film allows to probe the magnetic properties of an adjacent magnetic insulator via magnetotransport measurements. Here, we investigate th…
Topological Hall effect arising from the mesoscopic and microscopic non-coplanar magnetic structure in MnBi
Yangkun He, Sebastian Schneider, Toni Helm +9
The topological Hall effect (THE), induced by the Berry curvature, which originates from non-zero scalar spin chirality, is an important feature for mesoscopic topological structur…
Direct Observation of Plasmon Band Formation and Delocalization in Quasi-Infinite Nanoparticle Chains
Martin Mayer, Pavel L. Potapov, Darius Pohl +6
Chains of metallic nanoparticles sustain strongly confined surface plasmons with relatively low dielectric losses. To exploit these properties in applications,such as waveguides, t…
