Spin-disorder-induced angular anisotropy in polarized magnetic neutron scattering
I. Titov, M. Bersweiler, M. P. Adams +14
We experimentally report a hitherto unseen angular anisotropy in the polarized small-angle neutron scattering (SANS) cross section of a magnetically strongly inhomogeneous material…
Skyrmionic Schrödinger cat states in monoaxial chiral magnets
Stefan Liscak, Andreas Haller, Andreas Michels +2
We study the low-energy excitation spectra of a spin-1/2 quantum Heisenberg model with a monoaxial Dzyaloshinskii-Moriya interaction. Using the density matrix renormalization group…
Stability and Nucleation of Dipole Strings in Uniaxial Chiral Magnets
Vladyslav M. Kuchkin, Nikolai S. Kiselev, Andreas Haller +3
We report on the stability of the magnetic dipole string (DS), a three-dimensional magnetic texture formed by two coupled Bloch points with opposite topological charges, separated…
Quantum and classical magnetic Bloch points
Vladyslav M. Kuchkin, Andreas Haller, Štefan Liščák +5
A Bloch point represents a three-dimensional hedgehog singularity of a magnetic vector field in which the magnetization vanishes. However, standard micromagnetic theory, developed…
Framework for Polarized Magnetic Neutron Scattering from Nanoparticle Assemblies with Vortex-Type Spin Textures
Michael P. Adams, Evelyn P. Sinaga, Stefan Liscak +1
Within the framework of the recently introduced multi-nanoparticle power-series expansion method for the polarized small-angle neutron scattering (SANS) cross section, we present a…
