Papers
Inverted Hysteresis, Magnetic Domains, and Hysterons
TL;DR: In this paper, the authors used magnetooptical Kerr effect magnetometry on extended samples to measure local hysteresis curves as a function of an externally applied field in a magnetostriction-free amorphous ribbon and an elliptical Permalloy film element.

Moll,Richard Schlitz,Sebastian T. B. Goennenwein,Lukas M. Eng,Rudolf Schaefer,Joachim Wosnitza,Claudia Felser,Jacob Gayles,Toni Helm +19 more
TL;DR: In this paper, magnetosensitive microscopy combined with electrical transport is used to detect the emergence of antiskyrmions in crystalline microstructures of Mn$_{1.4}$PtSn at room temperature.

Topological Hall effect arising from the mesoscopic and microscopic non-coplanar magnetic structure in MnBi
Yangkun He,Sebastian Schneider,Toni Helm,Jacob Gayles,Daniel Wolf,Ivan Soldatov,Horst Borrmann,Walter Schnelle,Rudolf Schaefer,Gerhard H. Fecher,Bernd Rellinghaus,Claudia Felser +11 more
TL;DR: In this article, the authors examined the Hall effect in both bulk and micron-sized lamellar samples of MnBi and showed that both the non-coplanar spin structure in the lattice and topologically non-trivial skyrmion bubbles are responsible for the THE, and that the dominant mechanism depends on the sample size.
Stray fields above artificial magnetic in-plane domains
Florian Ahrend,Dennis Holzinger,M. Fohler,M. Fohler,S. Pofahl,Ulrike Wolff,M. DeKieviet,Rudolf Schaefer,Rudolf Schaefer,Arno Ehresmann +9 more
TL;DR: In this article, the out-of-plane component of the magnetic stray field over a magnetically patterned exchange biased layer system was quantitatively determined by scanning µ-Hall measurements.
3-D Branching of Magnetic Domains on Compressed Si-Fe Steel With Goss Texture
TL;DR: In this article, the influence of applied compressive stress on the hysteresis curve and domain structure in conventional (110) [001] Fe-3%Si steel cut parallel to the rolling direction was studied.
