Dynamical mass generation for ferromagnetic skyrmions in two dimensions
D. Wang, Hans-Benjamin Braun, Yan Zhou
Magnetic skyrmions are topological magnetization textures that are characterized by the homotopy group of two dimensional spheres. Despite years of intensive research on skyrmions,…
Emergent electromagnetism induced by topological defects created during magnetization reversal in nanowires
M. Charilaou, H. -B. Braun, J. F. Loeffler
We report that the irreversible magnetization switching process in ferromagnetic nanoparticles is governed by the formation and dynamics of topological point-defects in the form of…
Macroscopic Quantum Tunneling of Ferromagnetic Domain Walls
Hans-Benjamin Braun, Jordan Kyriakidis, Daniel Loss
Quantum tunneling of domain walls out of an impurity potential in a mesoscopic ferromagnetic sample is investigated. Using improved expressions for the domain wall mass and for the…
