Photon correlation spectroscopy with heterodyne mixing based on soft-x-ray magnetic circular dichroism
Christopher Klose, Felix Büttner, Wen Hu +4
Many magnetic equilibrium states and phase transitions are characterized by fluctuations. Such magnetic fluctuation can in principle be detected with scattering-based x-ray photon…
Walker breakdown with a twist: Dynamics of multilayer domain walls and skyrmions driven by spin-orbit torque
Ivan Lemesh, Geoffrey S. D. Beach
Current-induced dynamics of twisted domain walls and skyrmions in ferromagnetic perpendicularly magnetized multilayers is studied through three-dimensional micromagnetic simulation…
Twisted domain walls and skyrmions in perpendicularly magnetized multilayers
Ivan Lemesh, Geoffrey S. D. Beach
We present an analytical theory to describe three-dimensional magnetic textures in perpendicularly magnetized magnetic multilayers that arise in the presence of magnetostatic inter…
Investigation of the Dzyaloshinskii-Moriya interaction and room temperature skyrmions in W/CoFeB/MgO thin films and microwires
S. Jaiswal, K. Litzius, I. Lemesh +10
Recent studies have shown that material structures, which lack structural inversion symmetry and have high spin-orbit coupling can exhibit chiral magnetic textures and skyrmions wh…
Field-free deterministic ultra fast creation of skyrmions by spin orbit torques
Felix Büttner, Ivan Lemesh, Michael Schneider +10
Magnetic skyrmions are currently the most promising option to realize current-driven magnetic shift registers. A variety of concepts to create skyrmions were proposed and demonstra…
Full phase diagram of isolated skyrmions in a ferromagnet
Felix Büttner, Ivan Lemesh, Geoffrey S. D. Beach
Magnetic skyrmions are topological quasi particles of great interest for data storage applications because of their small size, high stability, and ease of manipulation via electri…
