Jakub Zázvorka,Jakub Zázvorka,Florian Jakobs,Daniel Heinze,Niklas Keil,Sascha Kromin,Samridh Jaiswal,Samridh Jaiswal,Kai Litzius,Kai Litzius,Gerhard Jakob,Peter Virnau,Daniele Pinna,Karin Everschor-Sitte,Levente Rózsa,Andreas Donges,Ulrich Nowak,Mathias Kläui +17 more
TL;DR: In this article, the diffusion of skyrmions in a non-flat energy landscape shows exponential temperature dependence and can be used for a reshuffler device with potential application in probabilistic computing.
Journal ArticleDOI
Thermal skyrmion diffusion applied in probabilistic computing

TL;DR: In this article, the thermal dynamics of topologically stabilized magnetic skyrmion quasi-particles are investigated in a specially tailored low pinning multilayer material system, and a device is constructed to reshuffle a signal.
Journal ArticleDOI

TL;DR: In this paper, the authors studied the skyrmion Hall angle as a function of temperature and drive amplitude in ferromagnetic multilayers and provided a complete description of the SkHA in the full range of drive strengths.
Journal ArticleDOI

TL;DR: It is demonstrated how by tuning the phase stability, one can reliably generate skyrmions by short current pulses and stabilize them at zero field, providing new means to create and manipulate spin textures in engineered chiral ferromagnets.
Journal ArticleDOI

TL;DR: The addition of Se was found to be very effective in arresting the formation of sub-grain boundaries and its networks, significantly reducing Zn segregation, improving compositional homogeneity and resulting in much lower concentrations of Te inclusions/precipitates.
