Detection and characterization of a different type of topological excitations, namely the domain wall (DW) skyrmion, has received increasing attention because the DW is ubiquitous from condensed matter to particle physics and cosmology. Here we present experimental evidence for the DW skyrmion as the ground state stabilized by long-range Coulomb interactions in a quantum Hall ferromagnet. We develop an alternative approach using nonlocal resistance measurements together with a local NMR probe…

Magnetic domain wall skyrmions
It is well established that the spin-orbit interaction in heavy metal/ferromagnet heterostructures leads to a significant interfacial Dzyaloshinskii-Moriya interaction (DMI), which modifies the
Collective Excitations, NMR, and Phase Transitions in Skyrme Crystals
At Landau level filling factors near ν = 1, quantum Hall ferromagnets form a Skyrme crystal state with quasi-long-range translational and noncollinear magnetic order. We develop an effective low

Recently spin textures called skyrmions have been discovered in certain chiral magnetic materials without spatial inversion symmetry, and have attracted enormous attention due to their promising

Evidence for skyrmion crystallization from NMR relaxation experiments.
TLDR
The data show a remarkable correlation between the nuclear spin relaxation and localization, which suggests that the magnetic ground state near complete filling of the first Landau level may contain a lattice of topological spin texture, i.e., a Skyrmion crystal.
Topological defects and goldstone excitations in domain walls between ferromagnetic quantum Hall liquids
It is shown that the low-energy spectrum of a ferromagnetic quantum Hall liquid in a system with a multidomain structure generated by an inhomogeneous bare Zeeman splitting epsilon(z) is formed by
Magnetic skyrmions: advances in physics and potential applications
Magnetic skyrmions are small swirling topological defects in the magnetization texture. Their stabilization and dynamics depend strongly on their topological properties. In most cases, they are
