Reduced vortex descriptors linking polycrystallinity in magnetic nanoparticles with polarized magnetic small-angle neutron scattering
M. P. Adams, J. Leliaert, A. Michels +1
Analytical vortex models reduce polarized magnetic small-angle neutron scattering (SANS) from nanoparticle ensembles to a small set of texture descriptors. In this work, we apply t…
Polarized neutron scattering as a probe for vortex-type spin correlations in iron oxide multicore assemblies
Venus Rai, Ivan Titov, Elizabeth M. Jefremovas +11
We report an experimental investigation of the magnetic microstructure of iron oxide multicore assemblies by means of polarized small-angle neutron scattering (SANS). Guided by a r…
Angular anisotropy landscape of vortex ensembles in polarized small-angle neutron scattering
Michael P. Adams, Elizabeth M. Jefremovas, Andreas Michels
We present a symmetry-resolved classification of two-dimensional spin-flip small-angle neutron scattering (SANS) patterns arising from dilute ensembles of spherical nanoparticles h…
NuMagSANS: a GPU-accelerated open-source software package for the generic computation of nuclear and magnetic small-angle neutron scattering observables of complex systems
Michael P. Adams, Andreas Michels
We present NuMagSANS, a GPU-accelerated software package for calculating nuclear and magnetic small-angle neutron scattering (SANS) cross sections and correlation functions. The pr…
Minimal model for vortex nucleation and reversal in spherical magnetic nanoparticles
Michael P. Adams, Andreas Michels
Magnetic nanoparticles beyond the single-domain limit often develop vortex-like magnetization textures arising from the competition between exchange and magnetostatic energies. Whi…
